DETAILED DESCRIPTION
[0042] The following discussion and accompanying figures disclose a
sole structure for an article of footwear. Concepts associated with
the footwear disclosed herein may be applied to a variety of
athletic footwear types, including soccer shoes, baseball shoes,
football shoes, golf shoes, and hiking shoes and boots, for
example. Accordingly, the concepts disclosed herein apply to a wide
variety of footwear types.
[0043] For consistency and convenience, directional adjectives are
employed throughout this detailed description corresponding to the
illustrated embodiments. The term "longitudinal," as used
throughout this detailed description and in the claims, refers to a
direction extending a length of a sole structure, i.e., extending
from a forefoot portion to a heel portion of the sole. The term
"forward" is used to refer to the general direction in which the
toes of a foot point, and the term "rearward" is used to refer to
the opposite direction, i.e., the direction in which the heel of
the foot is facing.
[0044] The term "lateral direction," as used throughout this
detailed description and in the claims, refers to a side-to-side
direction extending a width of a sole. In other words, the lateral
direction may extend between a medial side and a lateral side of an
article of footwear, with the lateral side of the article of
footwear being the surface that faces away from the other foot, and
the medial side being the surface that faces toward the other
foot.
[0045] The term "horizontal," as used throughout this detailed
description and in the claims, refers to any direction
substantially parallel with the ground, including the longitudinal
direction, the lateral direction, and all directions in between.
Similarly, the term "side," as used in this specification and in
the claims, refers to any portion of a component facing generally
in a lateral, medial, forward, and/or rearward direction, as
opposed to an upward or downward direction.
[0046] The term "vertical," as used throughout this detailed
description and in the claims, refers to a direction generally
perpendicular to both the lateral and longitudinal directions. For
example, in cases where a sole is planted flat on a ground surface,
the vertical direction may extend from the ground surface upward.
It will be understood that each of these directional adjectives may
be applied to individual components of a sole. The term "upward"
refers to the vertical direction heading away from a ground
surface, while the term "downward" refers to the vertical direction
heading towards the ground surface. Similarly, the terms "top,"
"upper," and other similar terms refer to the portion of an object
substantially furthest from the ground in a vertical direction, and
the terms "bottom," "lower," and other similar terms refer to the
portion of an object substantially closest to the ground in a
vertical direction.
[0047] For purposes of this disclosure, the foregoing directional
terms, when used in reference to an article of footwear, shall
refer to the article of footwear when sitting in an upright
position, with the sole facing groundward, that is, as it would be
positioned when worn by a wearer standing on a substantially level
surface.
[0048] In addition, for purposes of this disclosure, the term
"fixedly attached" shall refer to two components joined in a manner
such that the components may not be readily separated (for example,
without destroying one or both of the components). Exemplary
modalities of fixed attachment may include joining with permanent
adhesive, rivets, stitches, nails, staples, welding or other
thermal bonding, and/or other joining techniques. In addition, two
components may be "fixedly attached" by virtue of being integrally
formed, for example, in a molding process.
Footwear Structure
[0049] FIG. 1 depicts an embodiment of an article of footwear 10,
which may include a sole structure 12 and an upper 14. For
reference purposes, footwear 10 may be divided into three general
regions: a forefoot region 16, a midfoot region 18, and a heel
region 20. Forefoot region 16 generally includes portions of
footwear 10 corresponding with the toes and the joints connecting
the metatarsals with the phalanges. Midfoot region 18 generally
includes portions of footwear 10 corresponding with an arch area of
the foot. Heel region 20 generally corresponds with rear portions
of the foot, including the calcaneus bone. Regions 16, 18, and 20
are not intended to demarcate precise areas of footwear 10. Rather,
regions 16, 18, and 20 are intended to represent general relative
areas of footwear 10 to aid in the following discussion.
[0050] Since sole structure 12 and upper 14 both span substantially
the entire length of footwear 10, the terms forefoot region 16,
midfoot region 18, and heel region 20 apply not only to footwear 10
in general, but also to sole structure 12 and upper 14, as well as
the individual elements of sole structure 12 and upper 14.
[0051] As shown in FIG. 1, upper 14 may include one or more
material elements (for example, textiles, foam, leather, and
synthetic leather), which may be stitched, adhesively bonded,
molded, or otherwise formed to define an interior void configured
to receive a foot. The material elements may be selected and
arranged to selectively impart properties such as durability,
air-permeability, wear-resistance, flexibility, and comfort. An
ankle opening 22 in heel region 20 provides access to the interior
void. In addition, upper 14 may include a lace 24, which may be
utilized to modify the dimensions of the interior void, thereby
securing the foot within the interior void and facilitating entry
and removal of the foot from the interior void. Lace 24 may extend
through apertures in upper 20, and a tongue portion 26 of upper 14
may extend between the interior void and lace 24. Upper 14 may
alternatively implement any of a variety of other configurations,
materials, and/or closure mechanisms. For example, upper 14 may
include sock-like liners instead of a more traditional tongue;
alternative closure mechanisms, such as hook and loop fasteners
(for example, straps), buckles, clasps, cinches, or any other
arrangement for securing a foot within the void defined by upper
14.
[0052] Sole structure 12 may be fixedly attached to upper 14 (for
example, with adhesive, stitching, welding, and/or other suitable
techniques) and may have a configuration that extends between upper
14 and the ground. Sole structure 12 may include provisions for
attenuating ground reaction forces (that is, cushioning the foot).
In addition, sole structure 12 may be configured to provide
traction, impart stability, and/or limit various foot motions, such
as pronation, supination, and/or other motions.
[0053] The configuration of sole structure 12 may vary
significantly according to one or more types of ground surfaces on
which sole structure 12 may be used, for example, natural turf
(e.g., grass), synthetic turf, dirt, snow, synthetic rubber
surfaces (e.g., running tracks) and other indoor surfaces. In
addition, the configuration of sole structure 12 may vary
significantly according to the type of activity for which footwear
10 is anticipated to be used (for example, running, hiking, soccer,
baseball, football, and other activities).
[0054] Sole structure 12 may also vary based on the properties and
conditions of the surfaces on which footwear 10 is anticipated to
be used. For example, sole structure 12 may vary depending on
whether the surface is harder or softer. In addition, sole
structure 12 may be tailored for use in wet or dry conditions.
[0055] In some embodiments, sole structure 12 may be configured for
a particularly specialized surface and/or condition. For example,
in some embodiments, sole structure 12 may include a sole for a
soccer shoe configured to provide traction and stability on soft,
natural turf surfaces in wet conditions. In some such embodiments,
sole structure 12 may include, for example, a low number of ground
engaging members, wherein the ground engaging members are
aggressively shaped, and having a relatively large size.
Conversely, an alternative embodiment of sole structure 12 may be
configured to provide traction and stability on hard, artificial
turf surfaces in dry conditions. In some such embodiments, sole
structure 12 may include, for example, a larger number of ground
engaging members, which may be relatively smaller in size, and may
have less aggressive shapes. While the number, size, and shape of
ground engaging members are provided for exemplary purposes, other
structural parameters may be varied in order to tailor the shoe for
traction and stability on various surfaces, and/or in a variety of
conditions. Additional such parameters may include, for example,
the use of secondary traction elements, placement of ground
engaging members, the relative softness or hardness of the ground
engaging members and/or sole structure 12 in general, the relative
flexibility of portions of sole structure 12, and other such
parameters.
[0056] In some embodiments, sole structure 12 may be configured for
versatility. For example, sole structure 12 may be configured to
provide traction and stability on a variety of surfaces, having a
range of properties, and/or under various conditions. For example,
a versatile embodiment of sole structure 12 may include a medium
number of ground engaging members, having a medium size and
moderately aggressive shapes.
[0057] In addition to surface properties and conditions, sole
structure 12 may also be configured based on the physical
characteristics of the athlete anticipated to wear the footwear,
and/or according to the type of activity anticipated to be
performed while wearing the footwear. Football players, depending
on the position they play, can have a wide range of physical
characteristics and abilities. For example, linemen may be
relatively heavy, relatively slower, but also much more powerful
than players who play other positions. Linemen may place larger
loads on a sole structure that may be sustained over longer
durations, for example, up to one or two seconds, while engaging
with opposing linemen.
[0058] In contrast, skilled player positions, such as wide
receivers, may be relatively lighter weight, but much faster.
Skilled player positions, may place more explosive and transient
loads on a sole structure, via sprinting, cutting, and jumping, and
thus, may also maintain those loads for only a relatively short
duration (for example, a split second). Linebackers may have
physical characteristics and abilities that represent a combination
of the physical traits and abilities of linemen and wide receivers.
While linebackers may possess speed and agility and operate in open
field like a wide receiver, linebackers may also be larger,
heavier, and more powerful, and also engage other players in
tackling/blocking situations, like a lineman.
[0059] In view of the differing demands linemen and wide receivers
may place on sole structures, sole structures most suitable for
each type of player may be configured differently. For example, the
sole structures of linemen shoes may be configured to be more stiff
and durable, and also to distribute loads across the sole of the
shoe. In contrast, wide receiver shoes may have sole structures
that are configured for light weight, more selective flexibility
and stiffness at different areas of the foot, fast ground
penetration and egress by ground engaging members, and lateral
responsiveness. Further, a sole structure configured for use by a
linebacker may be more versatile, possessing compromises of
strength, stiffness, stability, light weight, directional traction,
and other characteristics.
[0060] Other types of activities may place similar and/or different
demands on a sole structure of a shoe. For example, soccer athletes
may place similar demands as wide receivers, that is, loads based
on speed and agility. Thus, soul structures having light weight,
responsiveness, fast ground penetration and egress, and traction in
a variety of directions and at a variety of ground contact angles
may be advantageous. In other sports, the demands may be more
focused. For example, sole structures configured for use by track
and field sprinters, who only run in a straight line at high speeds
and accelerations, may be configured for light weight, straight
line traction, and fast surface penetration and egress. In
contrast, a sole structure configured for hiking may be configured
quite differently. For example, a hiking sole structure may be
configured to provide stability over uneven surfaces, protection
from harsh surfaces (such as sharp rocks), traction on uphill and
downhill slopes, and grip on a variety of surfaces, for example,
natural turf, dirt, rocks, wood, snow, ice, and other natural
surfaces that may be traversed by a hiker.
[0061] The accompanying figures depict various embodiments of
cleated shoes, having sole structures suited for natural and/or
synthetic turf. Although footwear 10, as depicted, may be suited
for soccer, such a cleated shoe may be applicable for use in other
activities on natural and/or synthetic turf, such as baseball,
football, and other such activities where traction and grip may be
significantly enhanced by cleat members. In addition, various
features of the disclosed sole structures (and/or variations of
such features) may be implemented in a variety of other types of
footwear.
[0062] In some embodiments, sole structure 12 may include multiple
components, which may individually and/or collectively provide
footwear 10 with a number of attributes, such as support, rigidity,
flexibility, stability, cushioning, comfort, reduced weight, and/or
other attributes. In some embodiments, sole structure 12 may
include an insole 26, a midsole 28, a chassis 100, and a ground
engaging sole component 30, as shown in FIG. 1. In some cases,
however, one or more of these components may be omitted.
[0063] Insole 26 may be disposed in the void defined by upper 14.
Insole 26 may extend through each of regions 16, 18, and 20 and
between the lateral and medial sides of footwear 10. Insole 26 may
be formed of a deformable (for example, compressible) material,
such as polyurethane foams, or other polymer foam materials.
Accordingly, insole 26 may, by virtue of its compressibility,
provide cushioning, and may also conform to the foot in order to
provide comfort, support, and stability.
[0064] In some embodiments, insole 26 may be removable from
footwear 10, for example, for replacement or washing. In other
embodiments, insole 26 may be integrally formed with the footbed of
upper 14. In other embodiments, insole 26 may be fixedly attached
within footwear 10, for example, via permanent adhesive, welding,
stitching, and/or another suitable technique.
[0065] In some embodiments of footwear 10, upper 14 may surround
insole 26, including on an underside thereof. In other embodiments,
upper 14 may not extend fully beneath insole 26, and thus, in such
embodiments, insole 26 may rest atop midsole 28 (or atop chassis
100 in embodiments that do not include a midsole).
[0066] As noted above, footwear 10 is depicted in FIG. 1 as a
soccer shoe. Although soccer shoes often do not include a midsole,
since many features of footwear 10 may be applicable to shoes that
do include a midsole (including soccer shoes as well as shoes for
other activities), the general location of midsole 28 has been
depicted in FIG. 1 as it may be incorporated into any of a variety
of types of footwear (including soccer shoes if they do include
midsoles). Midsole 28 may be fixedly attached to a lower area of
upper 14 (for example, through stitching, adhesive bonding, thermal
bonding (for example, welding), and/or other techniques), or may be
integral with upper 14. Midsole 28 may extend through each of
regions 16, 18, and 20 and between the lateral and medial sides of
footwear 10. In some embodiments, portions of midsole 28 may be
exposed around the periphery of footwear 10. In other embodiments,
midsole 28 may be completely covered by other elements, such as
material layers from upper 14. Midsole 28 may be formed from any
suitable material having the properties described above, according
to the activity for which footwear 10 is intended. In some
embodiments, midsole 28 may include a foamed polymer material, such
as polyurethane (PU), ethyl vinyl acetate (EVA), or any other
suitable material that operates to attenuate ground reaction forces
as sole structure 12 contacts the ground during walking, running,
or other ambulatory activities.
Ground Engaging Sole Component
[0067] An article of footwear according to the present disclosure
may include a sole structure including a ground engaging sole
component fixedly attached to the upper. The sole component may
include features that provide traction and stability on any of a
variety of surfaces, and in any of a variety of conditions.
[0068] The sole component may be formed by any suitable process.
For example, in some embodiments, the sole component may be formed
by molding. In addition, in some embodiments, various elements of
the sole component may be formed separately and then joined in a
subsequent process. Those having ordinary skill in the art will
recognize other suitable processes for making the sole components
discussed in this disclosure.
[0069] The sole component may include a baseplate and one or more
ground engaging members extending downward from the baseplate. The
baseplate may include a substantially flat element that supports
the foot, and serves as a substantially rigid platform from which
the ground engaging members may extend.
[0070] FIG. 2 is a bottom perspective view of a first exemplary
embodiment of a ground engaging sole component 200 configured to be
fixedly attached to an upper in order to form an article of
footwear. FIG. 2 illustrates a bottom surface 205 of sole component
200 viewed from a rear-medial position.
[0071] Materials
[0072] The disclosed footwear components may be formed of any
suitable materials. In some embodiments, one or more materials
disclosed in Lyden et al. (U.S. Pat. No. 5,709,954), which is
hereby incorporated by reference in its entirety, may be used.
[0073] The components of the baseplate may be formed of any of a
variety of suitable materials. In some embodiments the baseplate,
the ground engaging members, and other elements of the sole
component may be integrally formed. For example, in some
embodiments, the entirety of the sole component may be formed of a
single material, forming all parts of the sole component. In such
embodiments, the sole component may be formed all at once in a
single molding process, for example, with injection molding.
[0074] Different structural properties may be desired for different
aspects of the sole component. Therefore, the structural
configuration may be determined such that, even though a common
material is used for all portions of the sole component, the
different portions may be stiffer, or more flexible due to
different shapes and sizes of the components. For example, the heel
and midfoot regions of the baseplate may be formed of a thicker
material and/or may include reinforcing features, such as ribs, in
order to provide stiffness to these portions of the sole component.
Whereas, the forefoot region of the baseplate may be formed of a
relatively thin material, in order to provide flexibility to the
forefoot region. Greater flexibility in a forefoot region may
enable natural flexion of the foot during running or walking, and
may also enable the sole component to conform to surface
irregularities, which may provide additional traction and stability
on such surfaces. In addition, the ground engaging members may be
formed with a thicker structure to provide rigidity and
strength.
[0075] In other embodiments, different portions of the sole
component may be formed of different materials. For example, a
stiffer material, such as carbon fiber, may be utilized in the heel
and/or midfoot regions of the baseplate, whereas a more flexible
material, such as a thin polyurethane, may be used to form the
forefoot region of the baseplate. In addition, it may be desirable
to utilize a stiffer and/or harder material for the baseplate, such
as carbon-fiber and/or polyurethane, and softer and more flexible
material for the ground engaging members, such as a relatively hard
rubber. Accordingly, in some embodiments, the sole component may be
formed by multiple molding steps, for example, using a co-molding
process. For instance, the baseplate may be pre-molded, and then
inserted into a sole component mold, into which the ground engaging
member material may be injected to form the ground engaging
members, or portions of the ground engaging members.
[0076] Sole component 200 may be formed of suitable materials for
achieving the desired performance attributes. Sole component may be
formed of any suitable polymer, composite, and/or metal alloy
materials. Exemplary such materials may include thermoplastic and
thermoset polyurethane (TPU), polyester, nylon, polyether block
amide, alloys of polyurethane and acrylonitrile butadiene styrene,
carbon fiber, poly-paraphenylene terephthalamide (para-aramid
fibers, e.g., Kevlar.RTM.), titanium alloys, and/or aluminum
alloys. In some embodiments, sole component 200 may be formed of a
composite of two or more materials, such as carbon-fiber and
poly-paraphenylene terephthalamide. In some embodiments, these two
materials may be disposed in different portions of sole component
200. Alternatively, or additionally, carbon fibers and
poly-paraphenylene terephthalamide fibers may be woven together in
the same fabric, which may be laminated to form sole component 200.
Other suitable materials and composites will be recognized by those
having skill in the art.
[0077] Baseplate
[0078] As shown in FIG. 2, sole component 200 may include a
baseplate 202. Baseplate 202 may be a substantially flat,
plate-like platform. Baseplate 202, although relatively flat, may
include various anatomical contours, such as a relatively rounded
longitudinal profile, a heel portion that is higher than the
forefoot portion, a higher arch support region, and other
anatomical features. In addition, baseplate 202 may include a
bottom surface 205, which may be generally flat, but may have
various contours that provide stiffness, strength, and/or
traction.
[0079] Ground Engaging Members
[0080] Sole component 200 may include one or more ground engaging
members 210 to provide traction and/or stability. It will be
understood that a variety of types of ground engaging members could
be implemented by sole component 200. Sole component 200 may
include ground engaging members having any of a variety of shapes,
sizes, and arrangements based on a number of factors. The
configuration of ground engaging members utilized for sole
component 200 may be based on the considerations discussed above,
for example, the physical attributes of the player, the nature of
the surface on which the activity is performed, and the conditions
of that surface.
[0081] In some cases, ground engaging members 210 could be
configured to engage a soft ground surface. For example, in one
embodiment, ground engaging members 210 could be configured to
engage a soft grass surface. In other cases, ground engaging
members 210 could be configured to engage a hard surface. For
example, in one embodiment ground engaging members 210 could be
configured to engage a hard grass surface or artificial turf. In
still other embodiments, other types of ground engaging members
could be used.
[0082] The ground engaging members may be configured to provide
traction and stability on any of a variety of surfaces, and in
under any of a variety of surface conditions. As depicted in FIG.
2, sole component 200 equipped with ground engaging members 210 is
a versatile sole structure, which may be suitable for a variety of
surfaces. For example, the ground engaging members shown in the
accompanying figures may be suited for a variety of relatively soft
surfaces, such as natural or cushioned synthetic turf, relatively
soft-packed dirt, and other compliant surfaces. However, the
features shown and discussed in the present disclosure may also be
applicable for relatively hard surfaces where cleated shoes may be
utilized. Exemplary such surfaces may include, for example,
relatively un-cushioned synthetic turf, hard-packed dirt or
cinders, such as may be found on a baseball field or a running
track, or synthetic rubber, such as may be found on other types of
running tracks.
[0083] Further, while sole component 200 could be configured for
any of various types of users, surfaces, and/or conditions, sole
component 200 (and other presently disclosed sole component
embodiments), as depicted in FIG. 2, is configured for speed and
agility, and may be suitable for lighter weight athletes
demonstrating, or looking to improve, speed and quickness. Sole
component 200 shown in FIG. 2 (and other presently disclosed sole
component embodiments) is depicted as a sole for a soccer shoe.
However, such a sole configuration, either as shown or with minor
modifications, could be utilized for other activities, such as
baseball, football, and/or other activities.
[0084] Exemplary disclosed ground engaging members may have one or
more features that facilitate ground penetration and/or ground
extraction. Such features may include, for example, shapes, sizes,
positioning on the sole component, as well as the orientation of
the ground engaging members. For example, in some embodiments, the
ground engaging members may have an elongate cross-sectional
horizontal shape. Further, the elongate shape may be narrower at
one end or the other. Such a narrower end may facilitate ground
penetration in the way a pointed implement is configured for ground
penetration. In addition, a narrower end may also facilitate ground
extraction (that is, the removal of the ground engaging member from
the ground after penetration).
[0085] As shown in FIG. 2, in some embodiments, ground engaging
members 210 may have a horizontal cross-sectional shape that is
substantially elongate. For example, as shown in cross sectional
view 215 in FIG. 2, ground engaging members 210 may have a
cross-sectional shape similar to an airfoil. In some embodiments,
an airfoil shape may be formed by virtue of having a slight
curvature, as shown in the figures, as well as differing widths at
the front and rear of the ground engaging member. For example, as
shown in cross-sectional view 215 in FIG. 2, ground engaging
members 210 may have a forward width 235 and a rearward width 240,
wherein forward width 235 is narrower than rearward width 240.
[0086] In some embodiments, forward width 235 may be approximately
0.5-4.0 mm, whereas rearward width 240 may be approximately 3.0-8.0
mm. These dimensions may vary depending upon the portion of sole
component 200 on which the ground engaging member is disposed. For
example, in some embodiments, a forefoot ground engaging member may
have a forward width 235 that is approximately 2.0 mm, and a
rearward width 240 that is approximately 5.0 mm. In contrast, in
some embodiments, a heel ground engaging member may have a forward
width 235 that is approximately 4.0 mm, and a rearward width 240
that is approximately 6.5 mm.
[0087] Exemplary elongate ground engaging members 210 may have a
length 245 that is substantially longer than either forward width
235 or rearward width 240. For example, in some embodiments, length
245 may be in the range of approximately 10.0-30.0 mm (1-3 cm). For
example, in some embodiments, forefoot ground engaging members may
have a length 245 of approximately 16 mm. This exemplary length 245
is at least three times larger than the width of any portion of the
exemplary forefoot ground engaging member dimensions mentioned
above. Also, in some embodiments, heel ground engaging members may
have a length 245 of approximately 20 mm. This exemplary length 245
is also at least three times larger than the width of any portion
of the exemplary heel ground engaging member mentioned above.
[0088] Other elongate shapes are also possible, such as oval,
rectangular, racetrack, and others. For example, FIGS. 3A and 3B
show an alternative elongate ground engaging member embodiment.
FIGS. 3A and 3B show a ground engaging sole component 300,
including a baseplate 302 having a bottom surface 305, and a
substantially curved ground engaging member 310. The radius of
curvature of ground engaging member 310 may be substantially
smaller than the radius of curvature of airfoil-shaped ground
engaging members 210. That is, ground engaging member 310 may be
more tightly curved than ground engaging member 210, as shown.
However, any suitable curvature may be used for ground engaging
members.
[0089] Exemplary ground engaging members may also include features
that provide additional traction in a region of the foot. For
example, additional traction may be desired in a region of a shoe
corresponding with the first distal phalanx of the foot. In some
embodiments, a ground engaging member may be utilized in this
region that has a substantially longer length. In such embodiments,
a ground engaging member may include dual downward projections. By
splitting the lengthened ground engaging member into dual
projections, ground penetration may be improved over a single long
projection. In addition, dual projections may be utilized to affect
weight distribution among ground engaging members.
[0090] Referring again to FIGS. 3A and 3B, ground engaging member
310 may include dual projections 315 with a bridge 320 between dual
projections 315. A ground engaging member having the configuration
of ground engaging member 310 may be incorporated at any suitable
location on a ground engaging sole component.
[0091] In some embodiments, the cross-sectional shape of ground
engaging members 210 may be substantially irregular. For example,
FIGS. 4A and 4B show an alternative ground engaging member
embodiment. FIGS. 4A and 4B show a ground engaging sole component
400, including a baseplate 402 having a bottom surface 405, and a
ground engaging member 410 having a tilde-shaped horizontal
cross-sectional shape.
[0092] Some embodiments may include ground engaging members having
features that facilitate weight reduction of the ground engaging
sole component. For example, some ground engaging members may have
holes passing through the ground engaging member, thus eliminating
extra material without substantially reducing strength or rigidity.
For Example, referring again to FIGS. 4A and 4B, in some
embodiments, ground engaging members 410 may include holes 415
passing through ground engaging members 410. Ground engaging
members having weight-reducing holes may be utilized in any
suitable locations on a sole component. Exemplary such locations
may include places where larger ground engaging members are
disposed. For example, heel regions often have longer cleats in
order to accommodate a raised heel region of the sole component as
discussed above. See, for example, FIG. 20. In addition, regions
where ground engaging members have been grouped closely, or where a
dual projection ground engaging member, such as ground engaging
member 310 shown in FIGS. 3A and 3B, may utilize holes in the
ground engaging members to reduce the amount of weight clustered in
that region of the shoe. See FIG. 19.
[0093] Ground engaging members may also have a substantially
regular cross-sectional shape. For example, in some embodiments,
ground engaging members may have a circular cross-sectional shape.
Circular ground engaging members may be less costly to produce, and
may also provide relatively even traction in all horizontal
directions. Circular round engaging members may also provide
traction, while still allowing rotation of a foot about the
circular ground engaging member while in contact with the ground.
This may facilitate pivoting on a planted foot, which may, in turn,
enable rapid changes in direction by the athlete, and promote
freedom of motion.
[0094] FIG. 5 illustrates an alternative ground engaging member
embodiment. For example, FIG. 5 shows a ground engaging sole
component 500, which may include a baseplate 502 having a bottom
surface 505, and a ground engaging member 510 having a
substantially round cross-sectional shape. In some embodiments,
ground engaging member 510 may be substantially conical, as shown
in FIG. 5. Substantially round ground engaging members may be
utilized at any suitable location of a sole component. In some
embodiments, round ground engaging members may be disposed at a
region of the sole component corresponding with the first
metatarsal head region of the wearer's foot and/or at the region of
the foot corresponding with a distal portion of the first phalanx.
See, for example, FIG. 19. An athlete may place a significant
amount of their weight on these regions of their foot when
pivoting. Therefore, placement of round ground engaging members at
these locations may facilitate pivoting, while still maintaining
traction.
Support Members
[0095] In addition to ground engaging members, a ground engaging
sole component may include one or more features to provide
reinforcement to the ground engaging members, increase traction,
and facilitate ground penetration and extraction. In some
embodiments the ground engaging sole component may include one or
more elongate support members extending downward from the bottom
surface of the baseplate of the sole component, abutting the side
portions of the ground engaging members, and extending horizontally
from the ground engaging members. Examples of such elongate support
members are disclosed in co-pending U.S. application Ser. No.
13/009,549, filed Jan. 19, 2011, entitled "Composite Sole
Structure," the disclosure of which is hereby incorporated by
reference in its entirety; and co-pending U.S. application Ser. No.
12/582,252, filed Oct. 20, 2009, entitled "Article of Footwear with
Flexible Reinforcing Plate," the disclosure of which is hereby
incorporated by reference in its entirety.
[0096] By spanning between ground engaging members and the bottom
surface of the baseplate, elongate support members may buttress,
brace, or otherwise reinforce the ground engaging members. This may
provide reinforcement, such as, for example, increased stiffness
and/or strength to the ground engaging members.
[0097] The amount of reinforcement provided by the elongate support
members may be dependent on the shape, size (length, height,
thickness), material, placement, and or orientation of the support
members. The amount of reinforcement provided may also depend on
the number of support members used on each ground engaging member.
The foregoing parameters may be varied to achieve the desired level
of reinforcement for a given ground engaging member. In some cases,
weight may be reduced by using a thinner, lighter weight ground
engaging member, while the strength and stiffness of the ground
engaging member may be maintained by the inclusion of one or more
elongate support members, which may provide the same amount of
strength and stiffness using less material.
[0098] Similarly, the reduction of material from the ground
engaging members may increase ground penetration. For example, when
elongate support members are used, the cross-section of the ground
engaging members may be reduced, allowing for increased ground
penetration. The addition of the support members provides little,
if any, additional impedance to ground penetration because the
support members are relatively thin, and thus readily penetrate the
ground. In addition, the support members may be configured such
that they do not extend the full length of the ground engaging
members, thus, a significant portion of the ground engaging members
may penetrate the ground before the support members even engage the
ground. Also, the support members may have a sloped configuration,
which may also facilitate ground penetration of the support members
themselves.
[0099] In addition to reinforcement and ground penetration, the
elongate support members may provide increased traction. As
additional elements that extend from the bottom surface of the sole
component baseplate, the support members may serve as secondary
traction elements. In addition, because the support members may be
elongate, the traction provided, like the reinforcement, is
substantially directional. That is, an elongate support member
provides the most traction in a direction perpendicular to the
direction in which it is elongated. Thus, the orientation of each
elongate support member may be selected to provide traction in a
desired direction at a desired region of the ground engaging sole
component. Accordingly, additional traction may be provided
specifically in a longitudinal (forward-rearward) direction or a
lateral (lateral-medial) direction, or at any angle between
longitudinal and lateral. It is noted that the direction in which
an elongate support member provides the most reinforcement is
perpendicular to the direction in which it provides the most
traction. This factor may be considered when selecting support
member configurations.
[0100] By extending one or more elongate support members
substantially radially (or at other angles) from a ground engaging
member, torsional traction may be provided about the ground
engaging member. Torsional traction is a characteristic that may be
either desirable or undesirable depending on the application. For
example, for certain activities, it may be beneficial to have
greater freedom of motion. Accordingly, for such activities, a
reduced size and/or number of support members may be utilized at
regions of the foot that may serve as pivot points during the
activity. For other activities, it may be desirable to provide
increased torsional traction in order to increase performance. For
example, it may be advantageous to provide a golf shoe with
increased torsional traction at certain portions of the foot, in
order to enable a golfer to generate more torque by twisting his
body during a swing.
[0101] In some cases, it may be advantageous on one foot to provide
increased torsional traction, and on the other foot to provide
decreased torsional traction. For example, while a golfer may want
additional torsional traction at one or more portions of his rear
foot (away from the hole) to enable him to execute a more powerful
swing, he may want a reduced amount of torsional traction at one or
more portions on his front foot (closer to the hole), to enable
greater freedom of motion. Depending on the portion of the foot in
question, the opposite may also be true. That is, it may be
desirable to provide one or more portions of the rear foot with a
reduced amount of torsional traction and provide one or more
portions of the front foot with an increased amount of torsional
traction.
[0102] Torsional traction systems may be advantageous for any type
of activity where it would be beneficial to generate torque with
the body. For example, increased agility may be provided by
enabling increased torque to be generated when changing directions.
In addition, other exemplary such activities may involve asymmetric
motions, such as throwing, swinging, kicking, and other motions.
Therefore, exemplary applications where torsional traction systems
could be implemented may include, for example, golf (as noted
above), baseball (both hitting and throwing), javelin, soccer (both
kicking).
[0103] The foregoing outlines a multitude of parameters regarding
the structural configuration of support members that may be
manipulated to provide desired reinforcement, ground penetration,
and traction characteristics at specific locations of the sole of
an article of footwear. Accordingly, the shape, size, material,
placement, orientation, and other specifications of each individual
support member may be chosen to achieve the desired performance
characteristics. This customization of multiple components of a
cleat system is reflected in the asymmetric and irregular support
member configurations in the disclosed embodiments. It is noted
that, as illustrated in the accompanying figures and described in
greater detail below, the shape, size, orientation, and other
parameters of support members may be inconsistent among ground
engaging members in the same sole structure embodiment. Further, it
should also be noted that, such variation may also exist among
support members about a common ground engaging member.
[0104] In addition, the configuration of support members may also
be varied according to the size of the article of footwear. For
example, larger sizes of footwear may use a similar arrangement of
ground engaging members. However, for larger shoe sizes (e.g., box
sizes), the spacing between the ground engaging members may be
significantly greater. Across a size range, the spacing between a
forefoot ground engaging member and a heel ground engaging member
may vary by several centimeters. In order to provide additional
traction in the larger spaces between ground engaging members for
larger shoe sizes, longer support members and/or support members
having an alternative shape may be utilized between the ground
engaging members. Similarly, it may be advantageous to alter the
configuration of support members by selectively reducing the size
of the support members in certain areas. For example, in some
embodiments, smaller sizes may include support members that
effectively bridge the entire gap between ground engaging members
by spanning between the members. However, for larger sizes, the
distance between two ground engaging members may be much larger
such that a support member that extends the full gap between the
ground engaging members may provide a level of traction that
exceeds the desired amount. In such cases, it may be beneficial to
omit the central portion of the bridging support member for larger
size footwear.
[0105] Shape of Support Members
[0106] The shape of support members may provide reinforcement,
ground penetration, and traction. The elongate configuration of
support members is discussed above as providing directional
reinforcement, directional traction, and ground penetration and
extraction. In addition, in some embodiments, other aspects of the
support member shape may influence these characteristics.
[0107] FIG. 6A illustrates an exemplary support member
configuration. As illustrated in FIG. 6A, a ground engaging sole
component 600 may include a baseplate 602 having a bottom surface
605, and a ground engaging member 610 extending downward from
bottom surface 605. Sole component 600 may also include one or more
elongate support members 630 extending substantially downward from
bottom surface 605 of baseplate 602, abutting ground engaging
member 610 at side portions thereof, and extending horizontally
from the side portions of ground engaging member 610.
[0108] In some embodiments, one or more of elongate support members
630 may include a downward facing surface 635 that is substantially
planar. It may be more cost effective to produce support members
with planar downward facing surfaces, as the molds may be simpler
to make. In addition, the mechanical properties of support members
having planar downward facing surfaces may also be simpler to
calculate, which may facilitate the process of developing a tread
system with the desired properties. Further, edges 660 between
downward facing surfaces 635 and vertical surfaces 640 of support
members 630 may provide additional traction over and above
alternative shapes, such as rounded downward facing surfaces.
[0109] In some embodiments, support members may have downward
facing surfaces that are sloped, for example, extending at angles
between the ground engaging members to the bottom surface of the
baseplate at locations that are relatively near, but spaced from,
the ground engaging member. These angles may be varied from support
member to support member and/or from ground engaging member to
ground engaging member. Further, in some embodiments, a single
ground engaging member may have a faceted downward facing surface,
wherein each facet is oriented at a different slope angle.
[0110] Different slope angles may provide different levels of
reinforcement by virtue of having the support provided at differing
angles, as well as by influencing the size of the support member.
In addition, slope angles may also affect ground penetration, with
steeper angles providing better ground penetration. In some
embodiments, faceted downward facing surfaces may have their
steepest portions (closest to vertical) nearest the ground engaging
member to which it is abutted. These portions that are closest to
the ground engaging members are furthest from the bottom surface of
the baseplate and, therefore, are the portions of the support
members that extend the furthest downward. Accordingly, as the sole
component comes into contact with the ground, these portions engage
the ground before (and therefore in more circumstances than) the
portions of the support members that are disposed further away from
the ground engaging members. In addition, the dual angles of a
support member may enable the traction provided by the support
members to be focused in the areas immediately surrounding the
ground engaging members, while still providing additional
reinforcement due to the wider extension of the portions of the
support members closer to the baseplate in directions horizontally
away from the ground engaging members.
[0111] It should be noted that the isolated depictions of first
elongate support member 645, second elongate support member 650,
and third elongate support member 655 in FIG. 6A are schematic and
are provided for dimensional illustration. While these components
could be implemented having shapes substantially as shown (with
profiles of right triangles), in some embodiments, the side
portions that abut the ground engaging member may have some degree
of curvature in conformity with the shape of the ground engaging
member, which can flare at a top portion where it abuts the bottom
surface of the baseplate.
[0112] In some embodiments, downward facing surfaces 635 may extend
at slope angles from the side portions of ground engaging members
630 to bottom surface 605 of baseplate 602 proximate to ground
engaging members 630. In some embodiments, downward facing surfaces
635 of elongate support members 630 may have slope angles that
differ from one another. For example, sole component 600 may
include a first elongate support member 645, a second elongate
support member 650, and a third elongate support member 655. As
shown in FIG. 6A, first elongate support member 645, second
elongate support member 650, and third elongate support member 655
may each have a different shape and/or size and, accordingly, may
have downward facing surfaces extending at different slope angles.
For example, elongate support member 645 may have a first height
H1, a first length L1, and a first slope angle .alpha.1 measured
with respect to horizontal. In addition, second elongate support
member 650 may have a second height H2, a second length L2, and a
second slope angle .alpha.2. Further, third elongate support member
655 may have a third height H3, a third length L3, and a third
slope angle .alpha.3. Exemplary approximate dimensions for the
foregoing components are provided in the table shown in FIG.
6B.
[0113] FIG. 7 illustrates an alternative exemplary support member
configuration. As shown in FIG. 7, a ground engaging sole component
700 may include a baseplate 702 having a bottom surface 705, and a
ground engaging member 710 extending downward from bottom surface
705. Sole component 700 may also include one or more elongate
support members 730 extending substantially downward from bottom
surface 705 of baseplate 702, abutting ground engaging member 710
at side portions thereof, and extending horizontally from the side
portions of ground engaging member 710. A peaked downward facing
surface may facilitate ground penetration of a support member.
[0114] In some embodiments, sole component 700 may include a peaked
elongate support member 735. As shown in FIG. 7, peaked elongate
support member 735 may have a downward facing surface 740 at least
a portion of which is substantially peaked. That is peaked elongate
support member 735 may have a downward ridge 740 at which opposing
faces of downward facing surface 745 may intersect.
[0115] FIG. 8 illustrates an alternative support member
configuration. FIG. 8 shows a ground engaging sole component 800,
which may include a baseplate 802 having a bottom surface 805, and
a ground engaging member 810 extending downward from bottom surface
805. Sole component 800 may also include one or more elongate
support members 830 extending substantially downward from bottom
surface 805 of baseplate 802, abutting ground engaging member 810
at side portions thereof, and extending horizontally from the side
portions of ground engaging member 810.
[0116] In some embodiments, one or more of elongate support members
830 may include a downward facing surface that is faceted. As shown
in FIG. 8, the downward facing surface may be faceted, such that
each facet extends at a different slope angle. For example, sole
component 800 may include a first elongate support member 835 and a
second elongate support member 840. First elongate support member
835 may have a downward facing surface 845.
[0117] In some embodiments, downward facing surface 845 may be
faceted. Downward facing surface 845 may include a first facet 850
and a second facet 855. In some embodiments, first facet 850 and
second facet 855 may be substantially planar. As shown in FIG. 8,
first facet 850 and second facet 855 may be angled at different
non-horizontal orientations. That is, first facet 850 and second
facet 855 may extend at different slope angles. For example, first
facet 850 may extend horizontally and upward from ground engaging
member 810 at a first slope angle 860, and second facet 855 may
extend horizontally and upward at a second slope angle 865.
[0118] In some embodiments, slope angles 860 and 865 may be
different. Further, in some embodiments, slope angles 860 and 865
may both extend at different non-horizontal orientations, as shown
in FIG. 8. In some embodiments, wherein first facet 850 is disposed
adjacent ground engaging member 810 and between ground engaging
member 810 and second facet 855, first slope angle 860 may be
steeper (closer to vertical) than second slope angle and 865, as
shown in FIG. 8.
[0119] The advantages of having support members that are elongate
are discussed in detail above. The degree to which a support member
is elongate is related to the thickness or horizontal width of the
support member. This thickness may vary from support member to
support member and/or from ground engaging member to ground
engaging member. Further, the thickness of each support member may
be consistent along its length or may vary. For example, in some
embodiments, the thickness may taper with distance from the ground
engaging member to which the support member abuts.
[0120] Referring again to FIG. 4A, in some embodiments, the
elongate support member may taper with distance from the ground
engaging member. For example, sole component 400 may include one or
more elongate support members 430. A first elongate support member
435 may include a horizontal length 440. In addition, first
elongate support member 435 may have a first horizontal width 445
(thickness) at an end proximal to ground engaging member 410, and a
second horizontal width 450 further away from ground engaging
member 410. In some embodiments, second horizontal width 450 may be
narrower than first horizontal width 445, and thus, may taper with
distance from ground engaging member 410.
[0121] Tapering support members may provide benefits in ground
penetration and extraction. As a ground engaging member penetrates
the ground, the force required to create further penetration may
increase. The added force required may be greater still if
additional parts of the sole component (such as support members)
come into contact with the ground as primary ground engaging
members penetrate. In some cases, it may be desirable to facilitate
deeper ground penetration, while maintaining the benefits of
support members. In such cases, it may be advantageous to provide
support members with tapered profiles, in order to better enable
ground penetration of the uppermost portions of the support
members.
[0122] Referring again to FIG. 5, sole component 500 may include
one or more elongate support members 530. A first elongate support
member 535 may have a horizontal length 540 and a horizontal width
545 (thickness). In some embodiments, horizontal width 545 may be
substantially the same over the entire horizontal length 540 of
first elongate support member 535.
[0123] It may be beneficial to form support members with a
consistent horizontal width in order to simplify manufacturing. A
consistent thickness may also provide consistent traction and
ground penetration related to the thickness, allowing traction and
ground penetration to be determined by other factors, such as slope
angle, orientation, and size of the support member.
[0124] Some embodiments may include an elongate support member that
has a lowermost surface that extends, over a first distance,
substantially horizontally away from the ground engaging member to
which it abuts. In some such embodiments, the support member may
project further downward over a second distance to form a second
ground engaging member.
[0125] Referring again to FIG. 7, sole component 700 may include a
second elongate support member 750. Second elongate support member
750 may include a lowermost surface 755. As shown in FIG. 7, second
elongate support member 750 may include a first portion 760 wherein
lowermost surface 755 extends substantially horizontally away from
ground engaging member 710. In addition, second elongate support
member 750 may include a second portion 765 wherein lowermost
surface 755 projects further downward to form a second ground
engaging member 770.
[0126] By providing a second ground engaging member depending from
a support member, ground engaging members may be clustered in a
particular area of the sole component. In addition, both the first
and second ground engaging members may benefit from the
reinforcement provided by the support member.
[0127] In some embodiments, one or more of the elongate support
members may have a curvature as it extends horizontally from the
ground engaging member to which it abuts. As shown in FIG. 7,
peaked elongate support member 735 extends horizontally from ground
engaging member 710 in a direction having a curvature. Peaked
elongate support member 735 may have a first radius of curvature
775. In addition, ground engaging member 710 may have a second
radius of curvature 780. As shown in FIG. 7, the curvature of
peaked elongate support member 735 may differ from the curvature of
ground engaging member 710. In addition, in some embodiments, the
curvature of peaked elongate support member 735 and the curvature
of the ground engaging member 710 may be reversed, as also depicted
in FIG. 7. Curved ground engaging members and/or curved elongate
support members may be applicable for use in any suitable location.
For example, such curved components may be suitable for use in
regions of the foot that are curved, such as at the junction
between the arch of the foot and the first metatarsal head.
[0128] Orientation of Support Members
[0129] While the amount of reinforcement, ground penetration,
and/or traction may be controlled by varying the shape of the
support members, as discussed above, the direction in which the
reinforcement and traction may be provided may also be controlled.
Each elongate support member may provide reinforcement and traction
in multiple directions. However, due to the elongate structure,
each elongate support member may provide the most reinforcement in
the direction of its elongation. For example, an elongate support
member that extends medially from a ground engaging member may
provide the greatest reinforcement in the lateral and medial
directions. Such a support member may, additionally, provide
reinforcement in forward and rearward directions, albeit to a
lesser degree. Thus, the direction of reinforcement provided by the
elongate support members may be controlled by selecting the
orientation of the support member. Similarly, the direction of
greatest traction provided by support members may be substantially
perpendicular to the direction of elongation.
[0130] In some embodiments, one or more support members may extend
substantially radially from an approximate center portion of a
ground engaging member. In some embodiments, one or more support
members may extend in a substantially non-radial direction. In some
embodiments, all support members abutting the same ground engaging
member may extend radially from the ground engaging member. In some
embodiments, all support members abutting the same ground engaging
member may extend in a substantially non-radial direction. Further,
in some embodiments, both radially and non-radially oriented
support members may abut the same ground engaging member.
[0131] FIG. 9 is a bottom view of a portion of a ground engaging
sole component 900. Sole component 900 may include a baseplate 902
having a bottom surface 905. Sole component 900 may also include a
ground engaging member 910. As shown in FIG. 9, ground engaging
member 910 may have a substantially elongate horizontal
cross-sectional shape. Sole component 900 may further include one
or more elongate support members 930. For example, as shown in FIG.
9, sole component 900 may include a first elongate support member
935, a second elongate support member 940, and a third elongate
support member 945. As shown in FIG. 9, first elongate support
member 935 and second elongate support member 940 may extend
substantially radially from an approximate center portion 950 of
ground engaging member 910.
[0132] Center portion 950 is intended to reflect an approximation
of the center of ground engaging member 910. In some embodiments,
the approximate center portion may relate to the geometric center
(centroid) of the ground engaging member. In other embodiments, the
center portion may simply be the intersection of lines bisecting
the length and width of the ground engaging member. As noted above,
however, the center portion is not necessarily intended to be a
precise center point according to any particular convention,
although it could be in some embodiments. Rather, the center
portion is intended to be approximate and is utilized in this
description to differentiate between support members that are
oriented substantially radially and support members that have a
substantially non-radial orientation.
[0133] As shown in FIG. 9, first elongate support member 935 may
extend along a first radial axis 955. Second elongate support
member 940 may extend along a second radial axis 960. First radial
axis 955 and second radial axis 960 may intersect center portion
950. Third elongate support member 945 may extend along a
substantially non-radial axis 965. As shown in FIG. 9, non-radial
axis 965 does not intersect with center portion 950. The use of
radial and/or non-radial support members may be based on
considerations discussed above regarding reinforcement, ground
penetration and extraction, and traction, including the
directionality of each of these properties.
[0134] In some embodiments, all support members abutting the same
ground engaging member may be radially oriented. In addition, both
radial and non-radial support members may abut ground engaging
members having any horizontal cross-sectional shape. FIG. 10
illustrates an alternative support member configuration. FIG. 10 is
a bottom view of a portion of a ground engaging sole component
1000. Sole component 1000 may include a baseplate 1002 having a
bottom surface 1005. Sole component 1000 may also include a ground
engaging member 1010. As shown in FIG. 10, ground engaging member
1010 may have a substantially round (circular) cross-sectional
shape.
[0135] Sole component 1000 may further include one or more elongate
support members 1030. For example, as shown in FIG. 10, sole
component 1000 may include a first elongate support member 1035, a
second elongate support member 1040, and a third elongate support
member 1045. As shown in FIG. 10, first elongate support member
1035, second elongate support member 1040, and third elongate
support member 1045 may all extend substantially radially from an
approximate center portion 1050 of ground engaging member 1010. For
example, as shown in FIG. 10, first elongate support member 1035
may extend along a first radial axis 1055. In addition, second
elongate support member 1040 may extend along a second radial axis
1060, and third elongate support member 1045 may extend along a
third radial axis 1065. First radial axis 1055, second radial axis
1060, and third radial axis 1065 may all intersect center portion
1050.
[0136] In some embodiments, wherein the ground engaging member is
elongate, support members may be selectively oriented to be either
in substantial alignment or substantial non-alignment with the
direction in which the ground engaging member is elongated. The
alignment of support members with elongate ground engaging members
may vary from support member to support member and/or from ground
engaging member to ground engaging member. For example, in some
embodiments support members may be consistently aligned or
non-aligned about a common ground engaging member to which all the
support members are abutted. In some embodiments, support members
may be consistently aligned or non-aligned throughout an
arrangement of ground engaging members. In other embodiments, both
aligned and non-aligned support members may be implemented in the
same arrangement of ground engaging members and/or even about the
same ground engaging member.
[0137] FIG. 11 illustrates another exemplary support member
configuration. FIG. 11 is a bottom view of a portion of a ground
engaging sole component 1100. Sole component 1100 may include a
baseplate 1102 having a bottom surface 1105. Sole component 1100
may also include a ground engaging member 1110. As shown in FIG.
11, ground engaging member 1110 may have a substantially elongate
cross-sectional shape.
[0138] Sole component 1100 may further include one or more elongate
support members 1130. For example, as shown in FIG. 11, sole
component 1100 may include a first elongate support member 1135, a
second elongate support member 1140, and a third elongate support
member 1145. As shown in FIG. 11, third elongate support member
1145, and at least one of first elongate support member 1135 and
second elongate support member 1140 may be independent of any other
ground engaging members extending from baseplate 1102.
[0139] As used in this detailed description and in the claims, the
term "independent," shall refer to a lack of interaction and/or
connection of an elongate support member with a ground engaging
member other than the ground engaging member to which it abuts.
Further, the term "independent" shall also refer to the lack of
interaction and/or connection of an elongate support member with
any other support members abutting another ground engaging
member.
[0140] Ground engaging member 1110 may be elongated along a ground
engaging member axis 1155. As shown in FIG. 11, first elongate
support member 1135 and second elongate support member 1140 may
each extend along an axis that is substantially aligned with ground
engaging member axis 1155. In addition, third elongate support
member 1145 may extend along a second support member axis 1160. As
shown in FIG. 11, second support member axis 1160, and thus second
elongate support member 1140, may be oriented in non-alignment with
ground engaging member axis 1155. Further, in some embodiments,
second elongate support member 1140 may be oriented substantially
perpendicular to ground engaging member axis 1155. As shown in FIG.
11, second elongate support member 1140 may be disposed at a first
angle 1165 with respect to ground engaging member axis 1155. In
some embodiments, first angle 1165 may be approximately 90 degrees.
First angle 1165 represents the angle between second elongate
support member 1140 and third elongate support member 1145. In
addition, a second angle 1170 represents the angle between first
elongate support member 1135 and third elongate support member
1145. Thus, in embodiments where third elongate support member 1145
is disposed substantially perpendicular to ground engaging member
axis 1155, second angle 1170 may be approximately 90 degrees.
[0141] Alternative embodiments, wherein an elongate support member
extends in a direction that is in substantial non-alignment with an
elongate ground engaging member, are depicted FIGS. 3A, 3B, and 7,
which are discussed above. As shown in FIGS. 3A and 3B, sole
component 300 may include an elongate support member 330 extending
from ground engaging member 310. Support member 330 may abut ground
engaging member 310 between dual projections 315 of ground engaging
member 310. See also elongate support member 730 in FIG. 7, which
may be oriented similarly with respect to dual projections 715 of
ground engaging member 710.
[0142] Referring again to FIG. 11, first elongate support member
1140 and second elongate support member 1145 may be disposed on
opposite sides of ground engaging member 1110, in substantial
alignment with ground engaging member axis 1155. Therefore, first
elongate support member 1140 and second elongate support member
1145 may be disposed in substantial alignment with each other.
Accordingly, in such embodiments, third angle 1175 may be
approximately 180 degrees.
[0143] In some embodiments, support members on opposite sides of a
ground engaging member may be substantially parallel to each other
without being in alignment with each other. FIG. 12 is a bottom
view of a portion of a ground engaging sole component 1200. Sole
component 1200 may include a baseplate 1202 having a bottom surface
1205. Sole component 1200 may also include a ground engaging member
1210. As shown in FIG. 12, ground engaging member 1210 may have a
substantially elongate cross-sectional shape.
[0144] Sole component 1200 may further include one or more elongate
support members 1230. For example, as shown in FIG. 12, sole
component 1200 may include a first elongate support member 1235, a
second elongate support member 1240, and a third elongate support
member 1245. First elongate support member 1235 and second elongate
support member 1240 may be disposed substantially on opposite sides
of ground engaging member 1210. First elongate support member 1235
may extend along a first axis 1255 and second elongate support
member 1240 may extend along a second axis 1260. In some
embodiments, first axis 1255 and second axis 1260 may be
substantially parallel with one another but not aligned with one
another, as shown in FIG. 12. For example, as shown in FIG. 12,
first axis 1255 and second axis 1260 may be separated by a distance
1265. In some embodiments, third elongate support member 1245 may
be omitted.
[0145] Spacing of Support Members
[0146] For many of the same reasons it may be desirable to have
spacing between ground engaging members that is chosen to achieve
certain performance parameters, it may also be desirable to select
spacing between support members about a common ground engaging
member. More closely spaced support members may provide
significantly increased reinforcement of ground engaging members
and may be suitable for providing traction on relatively hard
surfaces. Conversely, more spaced apart support members may provide
a less significant amount of reinforcement and may be more suitable
for relatively softer surfaces. In addition, in some embodiments,
the spacing about a ground engaging member may be substantially the
same between all support members abutting that ground engaging
member. In other embodiments, the spacing between such support
members may be uneven.
[0147] In some embodiments, spacing between three or more support
members abutting a common ground engaging member may be
substantially the same between each support member. For example,
referring again to FIG. 10, the spacing between elongate support
members 1030 may be substantially the same. For example, as shown
in FIG. 10, first elongate support member 1035 and second elongate
support member 1040 may be separated by a first angle 1070. Second
elongate support member 1040 and third elongate support member 1045
may be separated by a second angle 1075. In addition, third
elongate support member 1045 and first elongate support member 1035
may be separated by a third angle 1080. As illustrated in FIG. 10,
the spaces between elongate support members 1030 may be devoid of
additional support members. Since the spacing between elongate
support members 1030 may be substantially the same, in such
embodiments, first angle 1070, second angle 1075, and third angle
1080 may each be approximately 120 degrees.
[0148] Referring again to FIG. 11, in some embodiments, three or
more support members may be unevenly spaced about a common ground
engaging member to which the support members abut. As shown in FIG.
11, elongate support members 1130 may be unevenly spaced about
ground engaging member 1110. In some embodiments, first angle 1170
and second angle 1175 may be substantially different than third
angle 1180, as discussed above. Also, as illustrated in FIG. 11,
the spaces between elongate support members 1130 may be devoid of
additional support members. In addition, each of elongate support
members 1130 may be independent of other ground engaging members
included on sole component 1100.
[0149] It should be noted that, although FIG. 10 depicts evenly
spaced support members about a round ground engaging member and
FIG. 11 depicts unevenly spaced support members about an elongate
ground engaging member, spacing is not necessarily tied to the
shape of the ground engaging member. Therefore, embodiments are
envisaged wherein evenly spaced support members are disposed about
an elongate ground engaging member, and likewise, embodiments are
conceived wherein unevenly spaced support members are disposed
about a round ground engaging member.
[0150] Sizing of Support Members
[0151] As discussed above, the sizing of a support member may have
a significant effect on the amount of reinforcement, ground
penetration and extraction, and traction provided by the support
member. Accordingly, the sizing of each support member may be
selected according to considerations discussed above in order to
achieve desired performance characteristics.
[0152] In some cases variations in support member shape may
influence the size of the support member. FIG. 6A illustrates how
differences in shape may dictate changes in size. For example, as
shown in FIG. 6A, each of support members 630 may have
substantially the same height. That is, H1, H2, and H3 may be
substantially the same. However, by varying the length of support
members 630 about ground engaging member 910, support member 630
may be given a different shape. Since the height is the same across
all three support members 630, changing the length of the support
member results in a difference in overall size of the support
member (and the amount of material used to form the support
member). That is, in this case, the triangular surface area of
vertical surfaces 640 respectively increases and decreases with
increases and decreases in support member length. Therefore, not
only do the changes in shape influence the reinforcement, ground
penetration, and traction, but also the changes in shape can result
in changes in support member size, which can also influence these
characteristics. In other embodiments, the changes in shape may be
substantially more complex, and so too can the resulting changes in
size.
[0153] It should also be noted that even support members having
substantially the same dimensions (e.g., length, width, and
height), may have minor differences in overall size due to
irregularities in the surfaces of the components to which the
support members abut. For example, contours of the bottom surface
of the baseplate, as well as the flaring of the ground engaging
members near the junction between the ground engaging members and
the baseplate may dictate small variations in the overall sizes of
support members abutting these components. In addition, the angle
at which a support member adjoins, for example, an elongate ground
engaging member may influence the size of the support member. For
example, if an elongate support member adjoins an elongate ground
engaging member at a non-perpendicular angle, one side of the
support member may be longer than the other. These subtle
variations in shape and size may or may not have a significant
effect on the resulting reinforcement, ground penetration and
extraction, and traction provided by the support members.
[0154] As discussed above, in some embodiments, it may be
advantageous, for various reasons, to have the configuration of
each support member about a common ground engaging member to be
substantially the same. In other embodiments, it may be beneficial
for the configurations to differ. As discussed above, it may be
advantageous to have the orientation of supporting members to be
consistent or inconsistent about a common ground engaging member,
depending on the desired performance characteristics. The
orientation of support members may be selected independently of the
size and shape of the support members, although all of these
parameters may have collective effects on the reinforcement, ground
penetration and extraction, and traction. Similarly, the sizing of
support members may be selected independently of shape and
orientation. For example, the sizing of support members about a
common ground engaging member may be consistent, despite any
inconsistency in the orientation of the support members. In some
embodiments, the support members about a common ground member may
be inconsistently oriented, for example, the support members may be
unevenly spaced about the ground engaging member and/or some of the
support members may be radially oriented and others may be
non-radial. In such embodiments, the sizing (and/or shape) of the
support members may be consistent.
[0155] FIG. 9 illustrates an exemplary embodiment, wherein support
members 930 having the same size are disposed about ground engaging
member 910.
[0156] Regarding the dimensions of support members 930, the heights
of support members 930 may be substantially the same. For example,
as shown in FIG. 9, first elongate support member 935 may have a
first height 982, second elongate support member 940 may have a
second height 984, and third elongate support member 945 may have a
third height 986, wherein first height 982, second height 984, and
third height 986 may be substantially the same.
[0157] As discussed above, it may be advantageous to have the
orientations and spacing of supporting members to be consistent or
inconsistent about a common ground engaging member in order to
provide certain desired performance characteristics. The size and
shape of support members may be selected independently of the
orientation and/or spacing of the support members.
[0158] Referring again to FIG. 10, support members 1030 may have
even spacing about ground engaging member 1010, and may also have
consistent orientations, wherein each of support members 1030 may
be oriented in a substantially radial direction. Nevertheless, even
as the spacing and orientation of support members 1030 may be
substantially consistent, and the shape of ground engaging member
1010 may be substantially regular (in this case round), the sizing
of support members 1030 may be substantially uneven. As shown in
FIG. 10, first elongate support member 1035 may have a first length
1082. In addition, second elongate support member 1040 may have a
second length 1084, and third elongate support member 1045 may have
a third length 1086. As shown in FIG. 10, first length 1082 of
first elongate support member 1035 may be substantially the same as
second length 1084 of second elongate support member 1040. However,
as also shown in FIG. 9, third length 1086 may be substantially
different (in this case longer) than first length 1082 and/or
second length 1084.
[0159] With further regard to the size of support members, the
thickness may be one of several significant factors that determine
the performance characteristics of an elongate support member. In
some embodiments, desired reinforcement, ground penetration and
extraction, as well as traction may be provided by elongate support
members having a width (thickness) in a horizontal direction that
is smaller than the width of the ground engaging member to which it
abuts. In some embodiments, the width of the support member may
also be smaller than the width of an elongate ground engaging
member to which it abuts.
[0160] Referring again to FIG. 11, one or more of support members
1130 may have a horizontal width that is narrower than ground
engaging member 1110. As shown in FIG. 11, ground engaging member
1110 may be substantially elongate along ground engaging member
axis 1155 oriented in a first horizontal direction. Ground engaging
member 1110 may have a ground engaging member width 1180 in a
second horizontal direction that is substantially perpendicular to
the first horizontal direction. As shown in FIG. 11, first elongate
support member 1135 may have a support member width 1182. As
further shown in FIG. 11, support member width 1182 may be smaller
than ground engaging member width 1180.
[0161] It is noted that, although a larger base width 1184 of
ground engaging member 1110 is illustrated in FIG. 11 (and in other
bottom views, such as FIGS. 9 and 10), base width 1184 corresponds
with a flared aspect at the top of ground engaging member 1110.
Consequently, the larger base width 1184 may be substantially
limited to the uppermost portion of ground engaging member 1110,
and thus, substantially the entire height of ground engaging member
1110 may have a thickness that approximates ground engaging member
width 1180. Other configurations are also possible.
[0162] With further regard to the size of support members, the
height of support members is one dimension that is a factor in the
ultimate size of support members. In some embodiments the height of
support members may be similar or the same as the height of the
ground engaging member to which the support members are abutted (a
configuration not shown in the accompanying figures). In other
embodiments, the height of support members may be shorter than the
height of the ground engaging member to which the support members
are abutted. For example, in some embodiments, support members may
extend downward from the bottom surface of the ground engaging sole
component less distance than the first ground engaging member
extends downward from the bottom surface of the ground engaging
sole component. Such a configuration may facilitate ground
penetration and/or ground extraction of the ground engaging members
due to the periphery of the ground engaging members being
unencumbered by additional elements at the tip portions of the
ground engaging members. The difference in the heights of the
support members and the ground engaging members may be selected in
order to achieve desired performance, such as desired levels of
reinforcement, ground penetration and extraction, and/or
traction.
[0163] FIG. 13 is a bottom, perspective view of a heel region of an
exemplary ground engaging sole component 1300. Sole component 1300
may include a baseplate 1302 having a bottom surface 1305. Sole
component 1300 may also include one or more ground engaging members
1310. For example, sole component 1300 may include a first ground
engaging member 1315 and a second ground engaging member 1320. Sole
component 1300 may further include one or more elongate support
members 1330.
[0164] As shown in FIG. 13, ground engaging members 1330 may have a
ground engaging member height 1335. That is, ground engaging member
1330 may extend downward from bottom surface 1305 of baseplate 1302
a distance equivalent to ground engaging member height 1335. In
addition support members 1330 may have a support member height
1340. That is, support members 1330 may extend downward from bottom
surface 1305 of baseplate 1302 a distance equivalent to support
member height 1340. In some embodiments, as shown in FIG. 13,
support members 1330 may extend downward from bottom surface 1305
of baseplate 1302 less distance than ground engaging members 1310
extend downward from bottom surface 1305 of baseplate 1302. That
is, support member height 1340 may be shorter than ground engaging
member height 1335. In some embodiments, at least one of support
members 1330 may extend more than half of the distance that ground
engaging members 1310 extend downward from bottom surface 1305 of
baseplate 1302, as shown in FIG. 13. In other embodiments, not
shown, support members 1330 may extend half the distance or less
than half the distance that ground engaging members 1310 extend
from bottom surface 1305 of baseplate 1302.
[0165] Although the embodiments illustrated in the accompanying
figures show support members about a common ground engaging member
to have substantially the same heights, it is envisaged that
certain embodiments may implement arrangements of support members
wherein the heights of support members about a common ground
engaging member are inconsistent.
[0166] Materials of Support Members
[0167] Suitable materials for forming ground engaging sole
components are described above. As noted above, different
components of the sole components may be formed of the same or
different materials. In some embodiments, at least one of a
plurality of support members abutting a common ground engaging
member may be formed of the same material as at least a portion of
the ground engaging member. This may facilitate the molding process
of the ground engaging sole components. In other embodiments, the
support members may be formed of a different material than the
ground engaging member to which the support members are abutted.
For example, it may be desirable to provide a support member that
is substantially more rigid than the ground engaging member. With
such a configuration, rigidity can be selectively provided to
different aspects of the ground engaging member, in similar ways
that the positioning, orientation, shape, and size of support
members may selectively alter the performance characteristics of
ground engaging members.
[0168] Further, in some embodiments, different portions of the same
ground engaging member may be formed of different materials. For
example, a ground engaging member may be formed of one material in
portions where support members abut the ground engaging member, and
may be formed of a different material in portions where support
members do not abut the ground engaging member. In some
embodiments, upper portions of ground engaging members, where
support members are abutted, may be formed of a first material,
whereas lower portions of ground engaging members, below the
downward-most portions of support members, may be formed of a
different material. The selection of these materials may be based
on the performance characteristics of the materials in terms of
providing strength, rigidity, ground penetration and extraction,
and traction. In some embodiments the lower portions (e.g., tip
portions) of ground engaging members may be formed of relatively
softer materials (e.g., hard rubber) than upper portions of the
ground engaging members. This may improve traction on various
surfaces, and may also resist wear on non-playing surfaces (e.g.,
pavement) before and after participating in the activities for
which the footwear is suited.
[0169] With further regard to FIG. 13, ground engaging members 1310
are illustrated as being divided vertically by a separator line
1345, which serves to delineate a ground engaging member upper
portion 1350 and a ground engaging member lower portion 1355. In
some embodiments, one or more of support members 1330 may be formed
of the same material as at least a portion of ground engaging
members 1310. For example, in some embodiments, support members
1330 may be molded simultaneously with upper portions 1350 of
ground engaging members 1310, which are the portions of ground
engaging members 1310 to which support members 1330 are abutted. In
other embodiments, ground engaging members 1310 and support members
1330 may be formed of different materials.
[0170] Further, whether the two components are formed of the same
material or not, the components may be joined after initial
formation of one or both of the components. For example, in some
embodiments, portions of sole component 1300, including baseplate
1302 and ground engaging members 1310, may be formed by a first
molding process. Then, in an assembly process, support members 1310
may be welded to the preformed sole component 1300. Alternatively,
in a second molding process, support members 1330 may be molded to
the preformed portions of sole component 1300.
[0171] In some embodiments the tip portions of ground engaging
members 1310 that extend below the downward-most portion of support
members 1330 may be formed of a different material than the rest of
ground engaging members 1310. For example, in some embodiments,
lower portions 1355 of ground engaging members 1310 may be formed
of a softer material than upper portions 1350 of ground engaging
members 1310.
[0172] It is also noted that lower portions 1355 of ground engaging
members 1310 may be replaceable. For example, lower portions 1355
may be removable cleat studs, which may be removably fastened to
upper portions 1350 using any suitable fastening system, such as
threads (such ground engaging members may sometimes be referred to
as "screw-ins"). Such a configuration may enable a user to replace
lower portions 1355, for example, when lower portions 1355 become
worn, and/or in order to substitute a differently configured lower
portion 1355. In some cases replacement lower portions 1355 may
have different shapes, sizes, and/or may be formed of different
materials.
[0173] Relationships with Other Ground Engaging Members
[0174] Support members may provide improved reinforcement, ground
penetration and extraction, and/or traction by virtue of the
relationship between support members abutting one ground engaging
member and the support members abutting a ground engaging member
(and/or with the other ground engaging member itself) in the same
arrangement. For example, in some cases, a common support member
may be abutted to more than one ground engaging member. In some
embodiments, for example, a support member may bridge between two
ground engaging members to thereby form a braced, and thus
reinforced, traction system. In some cases, the combination of the
two ground engaging members and the bridging support member may
provide strength, rigidity and/or traction in greater amounts than
the individual components would separately.
[0175] As shown in FIG. 13, elongate support member 1330 may extend
horizontally between first ground engaging member 1315 and second
ground engaging member 1320 abutting both. Further, support member
1330 may have a downward facing surface 1365. In some embodiments,
downward facing surface 1365 may include multiple facets. For
example, as shown in FIG. 13, downward facing surface 1365 may
include three facets. A first facet 1365 may be angled upward and
away from first ground engaging member 1315 in the direction of
second ground engaging member 1320. In addition, a second facet
1370 may be angled upward and away from second ground engaging
member 1320 in the direction of first ground engaging member 1315.
Further, a third facet 1375 may be disposed between first facet
1365 and second facet 1370. In addition, as shown in FIG. 13, third
facet 1375 may be substantially horizontal.
[0176] In some embodiments, sole component 1300 may further
includes second and third elongate support members 1380, 1382,
extending substantially downward from bottom surface 1305 of
baseplate 1302, abutting first ground engaging member 1315, and
extending horizontally from first ground engaging member 1315. In
addition, sole component 1300 may also include fourth and fifth
elongate support members 1384, 1386 extending substantially
downward from bottom surface 1305 of baseplate 1302, abutting
second ground engaging member 1320, and extending horizontally from
second ground engaging member 1320. As shown in FIG. 13, first,
second, third, and fourth support members 1380, 1382, 1384, and
1386 may be arranged to form an H configuration.
[0177] Bridging support member configurations may be utilized at
any suitable region of the foot. One exemplary location where the
added rigidity of a bridging support member may be advantageous may
include the heel region, as shown in FIG. 13. The heel region is
often desired to be a relatively stiff area of an article of
footwear. Further, as discussed above, the heel region is often
raised to a certain extent and, therefore, ground engaging members
in a heel region may be longer than in a forefoot region.
Accordingly, it may be beneficial to reinforce longer ground
engaging members in a heel region with a bridging support
member.
[0178] FIG. 14 is a bottom, perspective view of a heel region
having an alternative bridging support member embodiment. As
illustrated in FIG. 14, an exemplary ground engaging sole component
1400 may include a baseplate 1402 having a bottom surface 1405.
Sole component 1400 may also include one or more ground engaging
members 1410. Sole component 1400 may further include one or more
elongate support members 1430.
[0179] In some embodiments, support members 1430 may be arranged to
form an X configuration between ground engaging members 1410. Sole
component 1400 may include a front left ground engaging member
1435, a rear left ground engaging member 1440, a rear right ground
engaging member 1445, and a front right ground engaging member
1450. Each of these ground engaging members may have an elongate
support member abutted to it and extending horizontally inward
toward a lateral midline of sole component 1400. For example, a
front left elongate support member 1455 may extend from front left
ground engaging member 1435, a rear left elongate support member
1460 may extend from rear left ground engaging member 1440, a rear
right elongate support member 1465 may extend from rear right
ground engaging member 1445, and a front right elongate support
member 1470 may extend from front right ground engaging member
1450. Support members 1430 may extend inward and intersect at a
central portion 1475, thus forming an X configuration.
[0180] In some cases, it may be beneficial to dispose support
members such that they are independent of any other ground engaging
members. Further, it may be advantageous to orient support members
such that the direction in which they extend from the ground
engaging member to which they are abutted is not aligned with any
other ground engaging members. By maintaining independence between
different ground engaging members (and independence between the
support members abutting one ground engaging member and the support
members abutting other ground engaging members), spacing may be
provided that may improve traction, for example, on relatively
softer surfaces. Also keeping the components separate may prevent
an excess of rigidity from being established by virtue of linking
ground engaging members and the associated structures (for example,
the support members), for example, in areas of the sole component
where flexibility may be desired.
[0181] FIG. 15 is a bottom view of an exemplary ground engaging
sole component 1500. Sole component 1500 may include a baseplate
1502 having a bottom surface 1505, and one or more ground engaging
members 1510 extending from bottom surface 1505 of baseplate 1502.
Sole component 1500 may also include one or more elongate support
members 1530. In some embodiments, sole component 1500 may include
a first forefoot ground engaging member 1532, a second forefoot
ground engaging member 1534, a third forefoot ground engaging
member 1536, a fourth forefoot ground engaging member 1538, a first
heel ground engaging member 1540, and a second heel ground engaging
member 1542.
[0182] Support members 1530 may include, abutting first forefoot
ground engaging member 1532, a first elongate support 1545, a
second elongate support member 1550, and a third elongate support
member 1555. As shown in FIG. 15, first elongate support 1545 may
extend horizontally from first forefoot ground engaging member 1532
in a first direction indicated by a first axis 1560. Second
elongate support member 1550 may extend horizontally from first
forefoot ground engaging member 1532 in a second direction
indicated by a second axis 1565. Third elongate support member 1555
may extend horizontally from first forefoot ground engaging member
1532 in a third direction indicated by a third axis 1570. In some
embodiments, first axis 1560, second axis 1565, and/or third axis
1570 may be not aligned with any of ground engaging members 1510 on
sole component 1500, as shown in FIG. 15. As further shown in FIG.
15, in some embodiments all of the support members (1530) abutted
to the forefoot ground engaging members (1532, 1534, 1536, and
1538) may extend in directions that are not in alignment with any
other forefoot ground engaging members 1532, 1534, 1536, and 1538.
Axes are omitted from the other forefoot ground engaging members
besides first forefoot ground engaging member 1532 for purposes of
maintaining clarity of illustration. However, it will be
understood, that as depicted in FIG. 15, the support members
abutting second, third, and fourth forefoot ground engaging members
1534, 1536, and 1538 extend in substantial non-alignment with any
of the other forefoot ground engaging members extending from
baseplate 1502.
[0183] In some embodiments, the baseplate may have gaps or cutouts
in the plate in order to allow different regions of the baseplate
to flex in certain ways. It may be desirable, however, to maintain
strength and rigidity in the baseplate portions that are adjacent
to the gaps. In some embodiments, elongate support members may be
oriented in such a manner that not only do the support members
reinforce ground engaging members to which the support members are
abutted, but they may also reinforce regions of the ground engaging
sole component baseplate adjacent to a gap in the baseplate.
[0184] As shown in FIG. 15, sole component 1500 may have a first
gap 1575 adjacent to a protruding portion 1580. In some
embodiments, second elongate support member 1550, abutting first
forefoot ground engaging member 1532, may extend into first
protruding portion 1580 in order to provide reinforcement (strength
and/or rigidity). In addition, sole component 1500 may also include
a second gap 1582 adjacent to a second protruding portion 1584.
Sole component 1500 may also include a fourth elongate support
member 1586, abutting fourth forefoot ground engaging member 1536.
As shown in FIG. 15, fourth elongate support member 1586 may extend
into second protruding portion 1584 to provide reinforcement. Such
baseplate reinforcement may be provided by elongate support members
in any portions of the baseplate, including portions that are near
gaps in the baseplate, as well as portions that are relatively
distanced from gaps.
[0185] It may also be advantageous to implement elongate support
members to provide reinforcement to portions of ground engaging
members proximate to areas of ground engaging members from which
material is absent. For example, it may be beneficial to form a
ground engaging member, in some embodiments, with a hole in a
central portion in order to reduce weight. In such embodiments, it
may be desirable to provide the baseplate with an elongate support
member abutting the ground engaging member in alignment with the
hole. This may reinforce the ground engaging member in an area
where the amount of material forming the ground engaging member has
been reduced. While including such a support member may add weight
back into the sole component, the weight may be added in a manner
that provides reinforcement in a directional manner. In addition,
by moving the material to a support member, the material may be
used to also provide additional traction.
[0186] Referring again to FIGS. 4A and 4B, ground engaging member
410 may include hole 415 passing substantially horizontally through
ground engaging member 410. In addition, as shown in FIGS. 4A and
4B, elongate support member 430 may include an aligned support
member 455 abutting ground engaging member 410 in substantial
alignment with hole 415.
[0187] In some embodiments, it may be advantageous to have one or
more forefoot support members that extend in a relatively lateral
orientation. This may provide desired longitudinal traction, and
reinforcement of the baseplate in a central portion between lateral
and medial ground engaging members. In some embodiments, it may be
beneficial to extend the support members at slight angles relative
to the lateral-medial direction. For example, in some embodiments
generally laterally oriented support members in a forefoot region
of the baseplate may extend at relatively shallow angles. Laterally
oriented support members extending from first and second forward
ground engaging members may intersect at a point forward of a line
connecting first and second rearward ground engaging members.
Alternatively or additionally, laterally oriented support members
extending from first and second rearward ground engaging members
may intersect at a point rearward of a line intersecting first and
second forward ground engaging members.
[0188] FIG. 16 is a bottom view of the forefoot region of the
ground engaging sole component configuration shown in FIG. 15. As
shown in FIG. 16, second ground engaging member 1534 may include a
first laterally oriented support member 1588 abutting second ground
engaging member 1534 and extending laterally in a direction toward
a lateral midline 1589 of baseplate 1502, wherein the direction is
illustrated by a first lateral direction axis 1590. In addition,
third ground engaging member 1536 may include a second laterally
oriented support member 1592 abutting third ground engaging member
1536 and extending laterally in a direction toward lateral midline
1589 of baseplate 1502. First lateral direction axis 1590 and
second lateral direction axis 1594 may intersect at an intersection
point 1596. In some embodiments, intersection point 1596 may be
forward of a line connecting first forefoot ground engaging member
1532 and fourth forefoot ground engaging member 1538. The distance
between intersection point 1596 and the forward-most portion
(indicated by line 1599) of the line 1597 connecting first forefoot
ground engaging member 1532 and fourth forefoot ground engaging
member 1538 is illustrated as longitudinal distance 1598.
[0189] FIG. 17 is a bottom view of the forefoot region of an
exemplary ground engaging sole component. As shown in FIG. 17, sole
component 200 may include a first rearward ground engaging member
250, a second rearward ground engaging member 255, a first forward
ground engaging member 260, and a second forward ground engaging
member 265. In addition, sole component 200 may also include a
first laterally oriented support member 270 abutting first rearward
ground engaging member 250 and extending laterally in a direction
toward a lateral midline 272 of baseplate 202, wherein the
direction is illustrated by a first lateral direction axis 274. In
addition, sole component 200 may include a second laterally
oriented support member 276 abutting second rearward ground
engaging member 255 and extending laterally in a direction toward
lateral midline 272 of baseplate 202, wherein the direction is
illustrated by a second lateral direction axis 278. First lateral
direction axis 274 and second lateral direction axis 278 may
intersect at an intersection point 280. In some embodiments,
intersection point 280 may be rearward of a line 282 connecting
first forward ground engaging member 260 and second forward ground
engaging member 265. The distance between intersection point 280
and the rearward-most portion (indicated by line 290) of line 282
connecting first forward ground engaging member 260 and second
forward ground engaging member 265 is illustrated as longitudinal
distance 284.
[0190] For purposes of explanation, the orientation of support
members extending from forward ground engaging members is discussed
in conjunction with FIG. 16, and the orientation of support members
extending from rearward ground engaging members is discussed
separately in conjunction with FIG. 17. However, it should be noted
that, in the embodiment shown in FIG. 16, the rearward support
members may be oriented as shown in FIG. 17, and are depicted as
such in FIG. 16. The dimensioning illustrating this feature has
been omitted from FIG. 16 in order to maintain the clarity of the
drawing. Similarly, in the embodiment shown in FIG. 17, the forward
support members may be oriented as shown in FIG. 16, and are
depicted as such in FIG. 17. Again, the dimensioning illustrating
this feature has been omitted from FIG. 17 in order to maintain the
clarity of the drawing.
[0191] In some embodiments, it may be advantageous to include one
or more secondary traction features at various portions of the sole
component. In some embodiments, it may be beneficial to provide
such secondary traction features proximate to one or more ground
engaging members. In some cases, secondary traction features, such
as a textured traction surface may be disposed between elongate
support elements abutting and extending from a ground engaging
member.
[0192] FIG. 18 is a perspective bottom view of the sole component
embodiment shown in FIGS. 15 and 16. As shown in FIG. 18, sole
component 1500 may include first laterally oriented support member
1588, a forward-oriented elongate support member 1512, and an
additional elongate support member 1514 abutting and extend from
second forefoot ground engaging member 1534. In some embodiments,
as shown in FIG. 18, sole component 1500 may include a textured
element 1516, which may be disposed, at least in part, between
support members 1588 and 1512, and/or between support members 1512
and 1514.
[0193] Textured element 1516 may include textured traction surface
including a plurality of peaked ground engaging members 1518. (See
FIG. 1.) Peaked ground engaging members 1518 may have a height that
is substantially less than ground engaging members 1510. In some
embodiments, peaked ground engaging members 1518 may have a height
in the range of about 1.0-5.0 mm. In some cases, the height of
peaked ground engaging members 1518 may be in the range of about
1.5-2.5 mm, for example approximately 2.0 mm.
[0194] For purposes of this disclosure, the term "between," as used
in the context of the placement of textured elements between
support members, refers to being either "linearly between" or
"rotationally between" support members, as explained in the
following paragraphs.
[0195] In some embodiments, textured element 1516 may be disposed,
at least in part, linearly between support members. As illustrated
in FIG. 18, a linear boundary between support members 1588 and 1512
is illustrated by line 1520. As illustrated in FIG. 18, at least a
portion of textured element 1516 may be disposed within the linear
boundary delineated by line 1520. Thus, at least a portion of
textured element 1518 may be disposed linearly between support
members 1588 and 1512. That is, at least one line can be drawn
between support members 1588 and 1512 that crosses textured element
1518.
[0196] In some embodiments, textured element 1516 may be disposed
rotationally between support members. In some cases, a textured
element may be disposed rotationally between support members but
may not be linearly between the support members. As shown in FIG.
18, a linear boundary between support members 1512 and 1514 is
illustrated as line 1522. As further shown in FIG. 18, in some
embodiments, no portion of textured element 1518 may fall within
the boundary delineated by line 1522. However, a rotational
boundary between support members 1512 and 1514 may be indicated by
rotational line 1524. As indicated in FIG. 18, at least a portion
of textured element 1518 may be disposed within the rotational
boundary delineated by rotational line 1524. Thus, at least a
portion of textured element 1518 may be disposed rotationally
between support members 1512 and 1514.
[0197] FIG. 19 illustrates an exemplary ground engaging sole
component 1900. Several aspects of FIG. 19 are shown in other
figures, for example, FIGS. 5, 7, 10, and 14. In addition, various
features of sole component 1900 are discussed above in conjunction
with other embodiments.
[0198] FIG. 20 illustrates an exemplary ground engaging sole
component 2000. Several aspects of FIG. 20 are shown in other
figures, for example, FIGS. 3A, 3B, 4A, and 4B. In addition, many
of the features of sole component 2000 are discussed above in
conjunction with other embodiments.
[0199] Although many possible combinations of features are shown in
the accompanying figures and discussed in this detailed
description, many other combinations of the disclosed features are
possible. Therefore, it will be understood that any of the features
shown and/or discussed in the present disclosure may be implemented
together in any suitable combination.
[0200] Observable Functionality
[0201] The shapes and orientations of support members disclosed
herein, may be non-symmetrical, and/or irregular, and thus, may be
indicative to observers (for example, potential users) that the
shapes and orientations are purposeful for more than mere
aesthetics. The shape, placement, orientation, and/or size of
support members may indicate to users that the sole structure has
certain performance characteristics. For example, placement of a
support member abutting a ground engaging member may indicate that
the ground engaging member is reinforced. Further, the orientation
of the support member may indicate the direction in which the
ground engaging member has been reinforced.
[0202] In some cases, an athlete who has experienced a broken cleat
stud may be shopping for a shoe with stronger cleat studs. The
athlete may, when shopping for new shoes, find a shoe with a sole
structure having a cleat stud with one or more abutting support
members and assess that the cleat stud with abutting support
members may be reinforced. While the quantitative degree to which
the cleat stud is reinforced may not be evident from mere visual
observation, the visually-observable qualitative characteristic of
the cleat stud being reinforced may provide a basis upon which an
athlete may select a particular shoe.
[0203] In addition, the location and orientation of the support
member may indicate that additional traction is provided in a
direction generally perpendicular to the support member.
Accordingly, a potential user looking for a shoe having ground
engaging members with improved traction in a particular location
and/or direction may observe attributes of a sole structure that
provide the desired characteristics. For example, an athlete may
find that lateral traction is less than desired in a region of his
current shoes that corresponds with the distal portion of the first
phalanx. The athlete may, when shopping for a new shoe, observe
that an available shoe has a cleat stud in this region that
includes, abutting the cleat stud, one or more support members that
are oriented longitudinally. Accordingly, the athlete may be able
to assess that additional lateral traction may be provided by the
support members. While the quantitative amount of traction provided
by the support members may not be readily observed visually, the
visually-observable qualitative characteristic of directional
traction (specifically lateral in this case) may provide a basis
upon which an athlete may select a particular shoe.
[0204] Selection of shoes is discussed above as being associated
with a shoe purchase. However, the factors considered above in
conjunction with a purchase may also apply to choosing a shoe from
an owner's collection to use for a particular event. For example, a
user may find that additional lateral heel traction is beneficial
when playing on soft, wet turf. Accordingly, when choosing a shoe
for an event that is to be played on soft, wet turf, the athlete
may select, from his own shoe collection, a shoe having
longitudinally oriented support members abutting heel cleat
studs.
[0205] While various embodiments of the invention have been
described, the description is intended to be exemplary, rather than
limiting and it will be apparent to those of ordinary skill in the
art that many more embodiments and implementations are possible
that are within the scope of the invention. Accordingly, the
invention is not to be restricted except in light of the attached
claims and their equivalents. Also, various modifications and
changes may be made within the scope of the attached claims.
