Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to an article of footwear, and more
particularly a sports shoe with a water repelling member associated
with a gripping system.
[0003] 2. Description of Related Art
[0004] There are many sports activities that include kicking a
ball. Examples of such sports include soccer, football, rugby,
Australian-rules football, and kickball. Conventional sports shoes
that are available for these sports typically have an upper made of
natural or synthetic leather. Other materials such as nylon may
also be used. These conventional materials generally do not have
high coefficients of friction when contacting the ball, and can
fail to properly grip or contact the ball.
[0005] Features to increase friction between the ball and shoe have
been proposed. Randall (U.S. Pat. No. 3,525,165) teaches a
removable flap kicking aid that attaches to the front cleat studs
and the shoelaces, acting as a cover to the shoelaces. The
removable flap has a series of gripping protrusions that are
aligned along the longitudinal axis of the shoe.
[0006] Johnston (U.S. Pat. No. 5,437,112) and Lee et al. (U.S.
patent application 2004/0055183), both of which are incorporated by
reference in their entirety, teach sports shoes having protrusions
or strips along the sides of the front portion of the shoe.
[0007] There is a need in the art for a sports shoe having a
gripping element that is located at an optimal contact location for
generating power during kicking and having a gripping element that
provides an even or symmetrical contact area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0053] FIGS. 1 and 2 illustrate a preferred embodiment of article
of footwear 100. For clarity, the following detailed description
discusses a preferred embodiment, in the form of a soccer boot, but
it should be noted that the present invention could take the form
of any article of footwear including, but not limited to, soccer
boots, football shoes, rugby shoes, as well as other kinds of
shoes.
[0054] Article of footwear 100, also referred to as simply article,
preferably includes sole 101 and upper 102. Sole 101 may be made
from any suitable material, including but not limited to
elastomers, siloxanes, natural rubber, other synthetic rubbers,
aluminum, steel, natural leather, synthetic leather, or plastics.
Preferably, sole 101 includes provisions for providing cleat studs
199 or other traction elements that can enhance traction with the
ground. In a preferred embodiment, sole 101 includes cleat studs
199 that are incorporated into sole 101. However, other embodiments
may include removable cleats. In a preferred embodiment, sole 101
may use one or more features described in U.S. Pat. No. 6,973,746
to Auger et al., the entirety of which is incorporated by
reference. In exemplary embodiment, the cleat assembly described in
U.S. Pat. No. 6,973,746 is used in combination with article
100.
[0055] In some embodiments, sole 101 may be associated with upper
102. Upper 102 is preferably configured to receive a wearer's foot.
Generally, upper 102 may be made from any suitable material,
including but not limited to, for example, nylon, natural leather,
synthetic leather, natural rubber, or synthetic rubber. Generally,
upper 102 can be made of any suitable knitted, woven or non-woven
material.
[0056] In some embodiments, upper 102 may include shoe fastening
system 103. Preferably, shoe fastening system 103 may be used to
tighten upper 102 to a wearer's foot. Examples of shoe fastening
systems include, but are not limited to, laces, buckles, or
hook-and-loop fastening systems such as Velcro.RTM.. In a preferred
embodiment, shoe fastening system 103 includes lace 179 as well as
first strap 177 and second strap 178 attached to upper 102.
Preferably, lace 179 interacts with first strap 177 and second
strap 178. Additionally, shoe fastening system 103 may include
lateral lacing portion 104. Lateral lacing portion 104 is
preferably laterally spaced from the center of article 100. Using
this laterally spaced lacing configuration, shoe fastening system
103 is designed to avoid interference with gripping system 105.
[0057] In some cases, article of footwear 100 may be used in
athletic activities associated with a ball, such as a soccer ball.
In order to achieve better contact with the ball, and in some
cases, apply some curvature in the trajectory of the kick, it may
be necessary for the kicker to apply some spin to the ball.
Preferably, upper 102 may include provisions for enhancing the
ability to contact and control the ball when kicked.
[0058] In some embodiments, upper 102 may include gripping system
105 disposed along upper surface 106 of upper 102. Preferably,
gripping system 105 may include a plurality of gripping members. In
a preferred embodiment shown in the Figures, upper 102 includes
first gripping member 110, second gripping member 111, third
gripping member 112, fourth gripping member 113, fifth gripping
member 114, sixth gripping member 115 and seventh gripping member
116. Preferably, gripping members 111-116 are disposed in
concentric rings along upper surface 106, as seen in the Figures.
Gripping member 110 may be disposed in the center of these
concentric rings. In other embodiments, the number of gripping
members comprising gripping system 105 may vary.
[0059] In this preferred embodiment, gripping members 110-116 are
generally circular and have a ring-like or disk-like shape, however
in other embodiments, gripping members 110-116 may be formed as a
different shape, including but not limited to square, rectangular,
diamond, oval, star, as well as other shapes. In some embodiments,
gripping members 110-116 may be constructed in the shape of a
manufacturer's logo, an athletic team's logo, or other kinds of
patterns.
[0060] In the preferred embodiment, gripping members 110-116 may be
disposed on upper surface 106 and raised with respect to upper
surface 106. In this configuration, gripping members 110-116 are
designed to make initial contact with a ball before upper surface
106.
[0061] In some embodiments, gripping members 110-116 may be made of
a high friction material. Preferably, gripping members 110-116 are
made of a material with a higher coefficient of friction than upper
102. In some embodiments, materials may be used that enhance
gripping when in the presence of moisture. Examples of such
materials include, but are not limited to, roughened leathers,
rubbers, silastics, or any synthetic or natural elastomeric
material such as styrene-butadiene, or polyurethane. In a preferred
embodiment, gripping members 110-116 are made of rubber.
[0062] Generally, gripping members 110-116 may be any desired size
and may be spaced apart by intervals of varying distances.
Preferably, gripping members are sized and located so that the
contact area between gripping members 110-116 and a ball may be
optimized. Referring to FIG. 3, the spacing and dimensions of
gripping members 110-116 are illustrated schematically. Generally,
first gripping member 110 has a circular disk-like shape. In this
embodiment, gripping member 110 has a first width W1. Preferably,
the remaining gripping members 111-116 have a ring-like geometry.
In some embodiments, second gripping member 111 may have a second
width W2. In a preferred embodiment, gripping members 112-116 may
also have a width similar to second gripping member 111 and may
have a similar second width, W2. In other embodiments, the widths
of each gripping members 110-116 may vary.
[0063] By adjusting widths W1 and W2, the contact area between a
ball and gripping system 105 may be varied. Generally, a larger
contact area may increase grip and friction between a ball and
gripping system 105, while a smaller contact area may decrease
friction between a ball and gripping system 105.
[0064] Additionally, the spacing between each of the gripping
members 110-116 may vary. In this embodiment, gripping members 110
and 111 are separated by a first distance D1; gripping members 111
and 112 are separated by a second distance D2; gripping members 112
and 113 are separated by a third distance D3; gripping members 113
and 114 are separated by a fourth distance D4; gripping members 114
and 115 are separated by a fifth distance D5; and gripping members
115 and 116 are separated by a sixth distance D6.
[0065] These distances may be ordered from least to greatest as:
D1, D2, D3, D4, D5, D6. In other words, the spacing between two
adjacent gripping members preferably increases the further the
gripping members are from first gripping member 110. This
arrangement helps to provide a balance between friction and
control. Other distance arrangements can be used to vary the
response characteristics of gripping system 105.
[0066] Using this preferred spacing, increased friction may be
applied to a ball by gripping system 105 in regions where gripping
members 110-116 are closest. In this embodiment, gripping members
110-116 are closest in the region proximate first gripping member
110. Varying the distances between gripping members 110-116 may
vary the location of the regions of increased traction.
[0067] Preferably, gripping members 110-116 are elevated above top
surface 107. Specifically, gripping members are elevated to a
height that may optimize contact area between gripping members and
ball. In this embodiment, first gripping member 110 has first
height H1. Preferably, heights of gripping members 111-116 are
substantially similar to first height H1. In other embodiments, the
heights of gripping members 111-116 may vary. With this preferred
raised arrangement, gripping members 110-116 may be raised high
enough above top surface 107 to minimize contact between top
surface 107 and a ball, but not so high that gripping members
110-116 deform substantially upon contact with a ball. In some
embodiments, top surface 107 may be made of a microporous and/or
high performance material such as Gore-Tex.RTM. or can include a
Gore-Tex.RTM. layer. The use of Gore-Tex.RTM. in combination with
other features is optional and is not used in every embodiment.
[0068] In some cases, the placement of gripping members 110-116 on
upper 102 may further enhance a wearer's ability to contact a ball
and control the spin of the ball. Preferably, the centers of
gripping members 110-116 are disposed in a location or locations
that are optimal for contacting a ball. FIG. 3 is a preferred
embodiment of article of footwear 100 with foot 200 shown in
phantom disposed over article of footwear 100. Preferably, gripping
members 110-116 are disposed over the region of foot 200 where the
force transfer between foot 200 and a ball is optimal, and where
most wearers tend to kick a ball. In a preferred embodiment,
gripping members 110-116 may be centered on top surface 107 of
article of footwear 100 slightly medial to longitudinal 125 axis of
article of footwear 100. Using this configuration, article of
footwear 100 preferably provides enhanced gripping of a ball during
kicking, allow the user to easily apply spin in any direction.
[0069] FIG. 5 illustrates the orientation of gripping members
110-116 at a preferred location for transferring force from the
foot to the ball during kicking. In FIG. 5, which is a schematic
side view, article 100 is contacting ball 250. Preferably, gripping
members 110-116 are disposed on upper 102 in a manner that
maximizes the contact area between gripping members 110-116 and
ball 250. This large contact area preferably facilitates friction
between ball 250 and article 100.
[0070] Preferably, the contact area between the ball and the
article of footwear occurs evenly and possibly symmetrically. Even
distribution of the contact area provides the wearer of article 100
with the ability to firmly and positively contact ball 250. FIGS. 6
and 7 illustrate the even distribution of contact areas. In
contrast to the preferred even and symmetric distribution of
gripping system 105, related art protrusion or strips mounted to an
article of footwear may cause unpredictable deflection of a ball
during kicking. However, the preferred even and symmetric gripping
system 105 provides a firm and predictable contact area with ball
250.
[0071] FIGS. 5, 6 and 7 demonstrate the even and symmetric nature
of gripping system 105. FIGS. 5 and 6 show embodiments at an
instance of contact with ball 250, and FIG. 7 is an embodiment
showing article 100 and ball 300 after contact. In FIG. 7, ball 300
has been rotated, so that the contact pattern or area is visible.
As shown in FIG. 7, ball 300 includes a number of shaded regions
that represent one example of the portions of ball 300 that were
contacted by gripping system 105. It can be observed that the
contact area generally corresponds to gripping system 105.
[0072] As shown in FIG. 7, ball 300 includes first shaded region
310 that illustrates the contact area between ball 300 and first
gripping member 110. Also, ball 300 includes second shaded region
311 that illustrates the contact area between ball 300 and second
gripping member 111, third shaded region 312 illustrates the
contact area between ball 300 and third gripping member 112, fourth
shaded region 313 illustrates the contact area between ball 300 and
fourth gripping member 113, fifth shaded region 314 illustrates the
contact area between ball 300 and fifth gripping member 114, and
sixth shaded region 315 illustrates the contact area between ball
300 and sixth gripping member 115. It can be observed in FIG. 7,
that gripping system 105 provides an even and symmetric contact
pattern on ball 300. In this example, seventh gripping member 116
does not contact ball 300. However, it should be noted that seventh
gripping member 116 may contact ball 300 in other examples.
[0073] Spin may be applied to ball 300 by gripping members 110-115
when the spin is applied in a direction perpendicular to the
orientation of gripping members 110-115. For circular designs, all
directions moving away from or towards the center of the circle are
perpendicular to the circle. In a preferred embodiment, the
generally circular design of gripping system 105 allows spin to be
applied in any direction perpendicular to gripping members. Using
this configuration, spin can be placed on ball 300 in any direction
during kicking when article 100 is equipped with gripping system
105. This preferred configuration of article of footwear 100 gives
a kicker tremendous flexibility to place any direction of spin on
ball 300 that the situation requires.
[0074] In many cases, a gripping system may include provisions that
provide the wearer with the ability to apply different types of
spin. In the previous embodiments, the surfaces of the gripping
members were generally flattened or parallel to the top surface of
the outsole. In other embodiments, an article of footwear may
include gripping members with multiple surface orientations.
Generally, elevated gripping members may be provided with surface
orientations that maximize the contact area between the gripping
members and the ball. Preferably, these gripping member surfaces
are oriented to provide enhanced control of spin during kicking. In
particular, multiple surface orientations are provided for enhanced
control of spin with each surface orientation associated with a
certain type of kick or spin.
[0075] Referring to FIG. 8, article of footwear 350 includes sole
351 and upper 352. In this embodiment, upper 352 preferably
includes the following gripping members: first gripping member 355,
second gripping member 356, third gripping member 357, fourth
gripping member 358, fifth gripping member 359, sixth gripping
member 360, and seventh gripping member 361 disposed on upper
surface 353. Gripping members 355-361 may preferably be elevated
with respect to upper surface 353.
[0076] Additionally, gripping members 355-361 may have surfaces
that are oriented in a preconfigured direction. In particular, each
of the gripping members 355-361 may include a respective outer
surface. In the embodiment shown in FIG. 8, first gripping member
355 includes first surface 370, second gripping member 356 includes
second surface 371, third gripping member 357 includes third
surface 372, fourth gripping member 358 includes fourth surface
373, fifth gripping member 359 includes fifth surface 374, sixth
gripping member 360 includes sixth surface 375, and second gripping
member 361 includes seventh surface 376. In this embodiment,
surfaces 371-376 are preferably tilted towards first central
gripping member 355. It can be observed in FIG. 8, that the
forefoot or toe portions of surfaces 371-376 are oriented facing
proximal or towards the kicker. It can also be observed that all of
the surfaces are tilted in the same direction.
[0077] In another embodiment, the surfaces of the gripping members
may be tilted away from the central gripping member. Referring to
FIG. 9, article of footwear 400 includes sole 401 and upper 402.
Upper 402 preferably includes a plurality of gripping members
including: first gripping member 405, second gripping member 406,
third gripping member 407, fourth gripping member 408, fifth
gripping member 409, sixth gripping member 410, and seventh
gripping member 411 disposed on upper surface 403. Gripping members
405-411 may preferably be elevated with respect to upper surface
403.
[0078] Additionally, gripping members 405-411 may have surfaces
that are oriented in a preconfigured direction. In particular,
gripping members 405-411 may include corresponding first surface
420, second surface 421, third surface 422, fourth surface 423,
fifth surface 424, sixth surface 425 and seventh surface 426. In
this embodiment, surfaces 421-426 are preferably tilted away from
first gripping member 405. It can be observed in FIG. 9, that the
forefoot or toe portions of surfaces 421-426 are oriented facing
distal or away from the kicker. Similar to the embodiment shown in
FIG. 8, it can also be observed in FIG. 9 that all of the surfaces
are tilted in the same direction.
[0079] Each of the distinct gripping member surface orientations
shown in FIGS. 8 and 9 are preferably configured to give the kicker
optimal control of particular types of kicks. For example, the
embodiment shown in FIG. 8 including gripping member surfaces that
are oriented towards the central gripping member may be optimally
configured for imparting spin on the ball. In contrast, the
embodiment shown in FIG. 9 including gripping member surfaces that
are oriented away from the central gripping member may be
configured to deflect the ball downwards, keep hard shots low, and
prevent errant high balls.
[0080] In many cases, a gripping system may include provisions that
provide the wearer with the ability to apply different types of
spin depending on the region of the shoe contacting the ball. The
ability to apply different types of spin may occur during a sport
such as soccer, where a wearer of article of footwear may require
topspin on a ball kicked hard and may alternately require sidespin
on a ball that is passed. In a preferred embodiment, an article of
footwear includes a gripping system with multiple surface
orientations of the gripping members.
[0081] In the previous embodiments, the surfaces of the gripping
members were tilted in directions either towards the central
disk-shaped gripping member, or away from the central disk-gripping
member. In some embodiments, it may be desirable to have gripping
members with surfaces that are oriented in one direction at one
portion of the upper, and that are oriented in a different
direction at another portion of the upper. This feature may
facilitate a player's ability to apply different types of spins or
impart different types of trajectories to a ball.
[0082] Referring to FIGS. 10-13, in some embodiments, an article of
footwear preferably includes gripping members with two distinct
surface orientations configured to facilitate different types of
kicks. In this embodiment, upper 502 of article of footwear 500
includes first gripping member 505, second gripping member 506,
third gripping member 507, fourth gripping member 508, fifth
gripping member 509, and sixth gripping member 510, disposed on
upper surface 503. As shown in the Figures, the general arrangement
of gripping members 505-510 is similar to previous embodiments,
with gripping members 506-510 arranged in concentric rings around
first gripping member 505.
[0083] Preferably, each of the gripping members 506-510 is
associated with an outer surface that twists along the gripping
members. Third gripping member 507 provides the clearest example of
this preferred twisting arrangement. In some embodiments, third
gripping member 507 includes outward tilted surface 523 and inward
tilted surface 524. The orientation of outward tilted surface 523
is preferably away from first gripping member 505 at all points
along third gripping member 507. Likewise, the orientation of
inward tilted surface 524 is preferably towards first gripping
member 505 at all points along third gripping 507. In other words,
outward tilted surface 523 is preferably oriented similar to the
gripping surfaces 421-426 shown in FIG. 9, while inward tilting
surface 524 is preferably oriented similar to gripping surfaces
371-376 shown in FIG. 8.
[0084] In this embodiment, transition zone 532 defines a boundary
between outward tilted surface 523 and inward titled surface 524.
In the direction moving clockwise from first end 570 of third
gripping member 507, transition zone 532 can be considered the
region of twist along gripping member 507. As viewed from above in
FIG. 10, this twisting results in a shrinking of inward tilted
surface 524 and an enlarging of outward titled surface 523, in the
clockwise direction between first end 570 and second end 572. In a
preferred embodiment, transition zone 532 may not be a clearly
defined line as seen in the Figures, but rather a general region of
subtle transition.
[0085] In some embodiments, the remaining gripping members 506 and
508-510 may all include similar outwardly and inwardly tilting
surfaces. In particular, second gripping member 506 preferably
includes second outward tilting surface 521 and second inward
tilting surface 522 associated with second transition zone 531;
fourth gripping member 508 includes third outward tilting surface
525 and third inward tilting surface 526 associated with third
transition zone 533, fifth gripping member 509 includes fourth
outward tilting surface 527 and fourth inward tilting surface 528
associated with fourth transition zone 534; and sixth gripping
member 510 includes fifth outward tilting surface 529 and fifth
inward tilting surface 530 associated with fifth transition zone
535. For purposes of clarity all the outward tilting surfaces 521,
523, 525, 527 and 529 are generally grouped as first gripping
region 574. Likewise all the inward tilting surfaces 522, 524, 526,
528 and 530 are generally grouped as second gripping region
576.
[0086] Preferably, first gripping region 574 and second gripping
region 576 may be disposed on different portions of upper 502.
Generally, first gripping region 574 may be disposed on instep
portion 580 of upper 502, while second gripping region 576 may be
disposed on side portion 582 of upper 502. In this embodiment,
curve 542 is associated with the boundary between first gripping
region 574 and second gripping region 580.
[0087] As previously discussed, the outward tilting surfaces of
gripping members may generally tend to deflect a ball downwards.
Therefore, if a player wishes to keep the trajectory of a ball low,
they may kick a ball with instep portion 580 where first gripping
region 574 is disposed. As seen in FIG. 12, as ball 550 contacts
gripping members 508-510, ball 550 is disposed against first
gripping region 574. As the ball is kicked, first gripping region
574 is designed to impart a downward spin or trajectory.
[0088] Furthermore, as previously discussed, the inward tilting
surfaces of gripping members may generally tend impart additional
spin to a ball. Therefore, if a wearer wishes to curl the ball for
a pass or a curved shot, the wearer may kick a ball with side
portion 582 where second gripping region 576 is disposed. As seen
in FIG. 13, as ball 560 contacts gripping members 509 and 510, ball
560 is disposed against second gripping region 576. As the ball is
kicked, the leading edges of second gripping region 576, which are
generally sharp, help to impart additional spin, causing a curved
trajectory.
[0089] In the current embodiment, curve 542 has the shape of an arc
that is generally shaped like a medial edge of upper 502 at the
forefoot. With this configuration, first gripping region 574 is
disposed further towards side portion 582 at fourth gripping member
508 and fifth gripping member 509. This preferred arrangement may
be used by a player who wants to have equal ability to direct a
ball downwards using first gripping region 574 and apply curl to a
ball using second gripping region 576.
[0090] In other embodiments, however, the boundary between first
gripping region 574 and second gripping region 576, defined by
curve 542 may be modified. For example, a player such as a striker
or forward in soccer may be mostly kicking low passes or low
trajectory shots. Therefore, it may be preferable to have a
configuration where first gripping region 574 dominates upper 502
over second gripping region 576. FIG. 14 represents an alternative
embodiment of article of footwear 500 where curve 542 has an arc
that bulges significantly at fourth gripping member 508 and fifth
gripping member 509. Using this configuration, a player may make
use of a larger contact area of upper 502 from which to impart a
downward direction using first gripping member 574, while
kicking.
[0091] In still another embodiment, shown in FIG. 15, curve 542 may
not be an arc, but rather a straight line. In this embodiment, the
area of second gripping region 576 is increased over the previous
embodiments. This configuration may be useful for a mid-fielder or
other players that tend to pass more, as more of upper 502 is
covered by second gripping region 576.
[0092] In some embodiments, gripping members may include provisions
that help to increase friction or grip between the gripping member
and a ball. These provisions may include features disposed on the
upper surfaces of the gripping members. In some cases, the upper
surfaces of the gripping members may be roughened, cut or include
channels or grooves. It is also possible to provide protrusions or
small projections on the upper surfaces of the gripping members.
These various features can, in some cases, help to improve friction
or grip between the gripping member and a ball. Some of these
features are particularly helpful in adverse playing conditions.
For example, a roughened outer surface, or an outer surface with
grooves may help to improve friction during wet or rainy
conditions. The upper surface features for the gripping members can
be selected according to player preference or to match a certain
playing condition.
[0093] It is also possible to independently arrange the upper
surface feature of each gripping member. In other words, different
gripping members on the same article may have different upper
surface features. For example, it is possible that one gripping
member include a roughened upper surface, while another gripping
member on the same article include an upper surface with
protrusions. It is also possible to provide the same upper surface
feature to every gripping member on an article. The gripping member
upper surface feature can be applied to any of the embodiments
disclosed above.
[0094] In some cases, wet conditions could inhibit the
effectiveness of a gripping system where the gripping system
includes one or more gripping members. As previously discussed, in
some embodiments, the gripping system may include provisions to
increase friction, or maintain the level of friction experienced
during dry conditions, between the gripping members and a ball
during wet conditions. In a preferred embodiment, the gripping
system may be associated with a provision that prevents water from
adhering to the gripping system.
[0095] FIG. 16 is an exploded isometric view of a preferred
embodiment of article of footwear 1600. In this embodiment, upper
1604 of article of footwear 1600 may include gripping portion 1603.
The boundary of gripping portion 1603 is indicated in FIG. 16 by
first boundary 1607. Preferably, gripping portion 1603 may be
configured to receive a gripping system of some kind.
[0096] Preferably, gripping system 1602 is associated with upper
1604. Gripping system 1602 may include a plurality of gripping
members and mesh 1605. In a preferred embodiment, gripping system
1602 includes first gripping member 1610, second gripping member
1611, third gripping member 1612, fourth gripping member 1613,
fifth gripping member 1614, sixth gripping member 1615 and seventh
gripping member 1616. Preferably, in a similar manner to the
previous embodiments, gripping members 1611-1616 are disposed in
concentric rings. Gripping member 1610 may be disposed in the
center of these concentric rings. In other embodiments, the number
of gripping members comprising gripping system 1602 may vary.
[0097] Preferably, gripping members 1610-1616 may be attached to
one another via mesh 1605. Mesh 1605 may be any kind of material
including, but not limited to, natural fibers, artificial fibers,
natural rubbers or synthetic rubbers, as well as other kinds of
materials. In a preferred embodiment, mesh 1605 may be made of a
cloth material. In this embodiment, gripping members 1610-1616 may
be glued to mesh 1605. With this configuration, gripping members
1610-1616 may be arranged on mesh 1605 prior to the assembly of
gripping system 1602 with upper 1604.
[0098] Generally, the structural features, as well as the materials
used to make gripping system 1602, are similar to the features and
materials discussed with respect to the previous embodiments.
Preferably, the sizes, of gripping members 1610-1616, as well as
the widths between adjacent gripping members 1610-1616 may be
similar to the previous embodiments. Also, it should be understood
that any of the possible variations discussed with respect to
gripping systems of the previous embodiments could also apply to
gripping system 1602.
[0099] In some embodiments, article of footwear 1600 may be
associated with water repelling member 1650. The term `water
repelling member`, as used throughout this detailed description and
in the claims, refers to any device that is configured to repel
water. In particular, the term `water repelling member` refers to a
device that may be associated with an article worn on the feet that
is intended to repel horizontal water or water accumulated through
splashing over a localized portion of the article. In some cases,
for example, a water repelling member may not prevent ground water
from soaking through an article, since it is not disposed globally
over the entire outer surface of the article.
[0100] In the preferred embodiment, water repelling member 1650 may
comprise one or more layers. Preferably, water repelling member
1650 includes a layer of water proof or water resistant material.
In a preferred embodiment, water repelling member 1650 includes a
layer of expanded Teflon.RTM. and/or a Teflon.RTM. film. Water
repelling member 1650 could also include other layers, including
backing layers made of cloth or similar materials. Using a backing
material may allow water repelling member 1650 to be more easily
attached to upper 1604.
[0101] For purposes of clarity, water repelling member 1650 is
associated with article of footwear 1600. In other embodiments,
however, water repelling member 1650 could be associated with any
type of article configured to cover a wearer's foot. Examples of
other articles include, boots, booties, sandals, as well as other
articles. Preferably, water repelling member 1650 may be associated
with a gripping system of an article configured to cover a wearer's
foot.
[0102] In the current embodiment, water repelling member 1650 is
disposed between gripping system 1602 and gripping portion 1603 of
upper 1604. Furthermore, gripping system 1602 and water repelling
member 1650 generally have shapes that are coincident with each
other and with gripping portion 1603. With this arrangement, water
repelling member 1650 may be disposed just under gripping system
1602, once gripping system 1602 and water repelling member 1650
have been attached to gripping portion 1603 of upper 1604.
[0103] FIG. 17 is a preferred embodiment of article of footwear
1600 after gripping system 1602 and water repelling member 1650
have been attached to upper 1604. For clarity, a portion of upper
1604 has been shaded to indicate where water repelling member 1650
is disposed below gripping system 1602 throughout the Figures.
[0104] Generally, gripping system 1602 and water repelling member
1650 may be attached to upper 1604 using any method. In some
embodiments, water repelling member 1650 may be attached to upper
1604 first, using an adhesive or via stitching. Following this,
gripping system 1602 may be attached to water repelling member 1650
using an adhesive or stitching. In other embodiments, gripping
system 1602 may be attached to water repelling member 1650 before
water repelling member 1650 is attached to upper 1604.
[0105] In some embodiments, gripping system 1602 and water
repelling member 1650 may be attached to upper 1604 after article
of footwear 1600 has been assembled. In other embodiments, gripping
system 1602 and water repelling member 1650 may be attached to
upper 1604 before article of footwear 1600 has been assembled. For
example, gripping system 1602 and water repelling member 1650 could
be manufactured simultaneously with upper 1604, in some
embodiments.
[0106] Although the preferred embodiment of water repelling member
1650 shown in the Figures is substantially similar in size to
gripping system 1602, in other embodiments, water repelling member
1650 may cover more or less of article of footwear 1600. For
example, first alternative shape 1710 for a water repelling member
is shown to be smaller than gripping system 1602. This
configuration may be useful in cases where a player only expects to
contact the ball with a small portion of gripping system 1602
during kicks. Also, second alternative shape 1712 for a water
repelling member is shown to be larger than gripping system 1602.
This configuration may be useful in preventing horizontal water or
splashing from soaking through additional portions of the top of
upper 1604. Generally, as previously discussed, any size and/or
shape of a water repelling member may be accommodated. In other
words, gripping system 1602 and water repelling member 1650 need
not have the same size.
[0107] FIG. 18 is a cross sectional view of a preferred embodiment
of a portion of upper 1604, including gripping system 1602 and
water repelling member 1650. As shown in this Figure, gripping
system 1602 comprises gripping members 1612 and 1613 that are
disposed on top side 1802 of mesh 1605. Water repelling member 1650
is further disposed between bottom side 1804 of mesh 1605 and top
side 1806 of upper 1604. In this preferred embodiment, water
repelling member 1650 includes first layer 1810 and second layer
1812. First layer 1810 may be a layer of expanded Teflon.RTM., or
similar water proof material, as previously discussed and may be
attached directly to the gripping system. Second layer 1812 may be
a backing layer configured to attach first layer 1810 with upper
1604.
[0108] In prior designs, a water resistant material is generally
applied to the entirety of the article of footwear. In some cases,
where the water resistant material is applied to one portion of an
article of footwear, the water resistant material typically extends
over the bottom of the upper. This feature allows for the prior art
designs to resist soaking through of the article of footwear from
ground water. However, these designs may inhibit some flexibility
in the upper, especially at the bottom portion of the upper, since
the water resistant material is an extra layer on top of the base
upper material.
[0109] Unlike prior designs, water repelling member 1650 is
preferably localized over article of footwear 1600. In other words,
water repelling member 1650 preferably only covers a portion of
article of footwear 1600, rather than the entirety of article of
footwear 1600. In the current embodiment, water repelling member
1650 is preferably disposed only on gripping portion 1603 of
article of footwear 1600 (see FIG. 16) that is associated with
gripping system 1602.
[0110] Referring to FIGS. 19-20, water repelling member 1650
preferably does not overlap with a bottom surface of upper 1604. In
the current embodiment, upper 1604 preferably includes transition
region 1904 that extends over first side 1906 and second side 2006
of article of footwear 1600. Transition region 1904 is preferably
the region where outsole 1903 joins with upper 1604. In particular,
transition region 1904 includes bottom surface 1902 of upper
1604.
[0111] Water repelling member 1650 preferably includes outer
periphery 1910. In this preferred embodiment, transition region
1904 and outer periphery 1910 are separated by a distance D7 or
greater on first side 1906 and a distance D8 or greater on second
side 2006. D7 preferably represents the distance between transition
region 1904 and the portion of outer periphery 1910 that is lowest
to the ground on first side 1906. Likewise, distance D8 preferably
represents the distance between transition region 1904 and the
portion of outer periphery 1910 that is lowest to the ground on
second side 2006. In other words, water repelling member 1650 is
spaced from transition region 1904. With this arrangement, water
repelling member 1650 does not extend to bottom surface 1902 of
upper 1604, since bottom surface 1902 of upper 1604 is disposed
within transition region 1904. This preferred arrangement allows
for increased flexibility of upper 1604 over prior designs where a
water resistant material is applied over a region of the bottom
surface of an upper, reducing flexibility in this region.
[0112] For clarity, the current embodiment includes flattened
gripping members. In other embodiments, however, water repelling
member 1650 could be associated with gripping members including
multiple surface orientations, such as many of the previous
embodiments of a gripping system. Generally, water repelling member
1650 could be associated with any type of gripping system that is
configured to facilitate increased control in kicking for a
user.
[0113] FIGS. 21-23 are a preferred embodiment of article of
footwear 1600 including gripping system 1602 intended to illustrate
the function of water repelling member 1650. In the embodiment
shown here, athlete 2202 is stepping into puddle 2204. As article
of footwear 1600 is placed into puddle 2204, water is generally
displaced, resulting in a small upwards and horizontally directed
splash 2206. FIG. 22 is a close up of a preferred embodiment of a
portion of article of footwear 1600 immediately following this
splashing. It is clear from FIG. 22 that water beads 2302 have
formed on first portion 2304 of upper 1604, where first portion
2304 does not include water repelling member 1650. However, second
portion 2306 of upper 1604 which includes water repelling member
1650, does not include any water beads. In other words, water has
been repelled from water repelling member 1650. Although only a
portion of gripping system 1602 is shown in FIG. 22, it should be
understood that water is generally repelled from all portions
associated with gripping system 1602 which is disposed above water
repelling member 1650.
[0114] FIG. 23 is a preferred embodiment of an athlete kicking ball
2402 just after article of footwear 1600 has experienced splashing.
While the majority of upper 1604 includes water beads 2302,
gripping system 1602, which is disposed above water repelling
member 1650, is generally dry. Therefore, as ball 2402 contacts
gripping system 1602, ball 2402 may not slip on gripping members
1610-1616, allowing for gripping system 1602 to remain, fully or
close to fully, functional in wet conditions.
[0115] 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.
