Running: "How Humans Ran Comfortably and Safely Before the
Invention of Shoes", ScienceDaily Feb. 1, 2010, Harvard University
[0005] McDougall, C. Born to Run Alfred A. Knopf, New York, 2009
[0006] Munson, L. The Soldier's Foot and Military Shoe, George
Banta Publishing, 1917
[0007] Prior to World War I (WWI) an extensive investigation by the
Army Shoe Board of two thousand soldiers' feet, careful examination
and fitting of thousands more, including x-raying their feet in
their boots revealed that less than ten percent of the soldier's
feet to be in good condition. The rest suffered painful foot
injuries some debilitating. By shoe manufactures simply added a
quarter inch or more room on the medial side of the great toe on
standard military and civilian shoes made shoes fit naturally and
flex comfortable. This simple remedy dramatically reduced shoe
caused foot injuries for both soldiers and civilians. Shoe caused
foot injuries remained relatively low and stable until the
invention of modern running shoes during the running boom in the
1970's.
[0008] Recent studies indicate that well over fifty percent of
runners are injured at any one time and that eight out of every ten
runners are hurt every year. The designs of typical athletic shoes
are the primary source of running injuries. Proponents of barefoot
running claim that it causes fewer injuries than wearing athletic
running shoes. Barefoot runners typically run softly, landing on
the midfoot or balls of their feet called forefoot striking. Shoed
runners typically land on their heels, heel striking. Modern
Running shoes deceptively feel comfortable but are contributing to
a wide variety of injuries, including but not limited to foot,
ankle, knee, and hip injuries. Placing various amounts of sponge
like padding under the heels of runners enables them to quickly
increase their running mileage by landing on their heels. In doing
so, the foot's natural motion is impeded and the foot arches and
lower leg are not able to adequately absorb the shock of the
landing. The shock moves from the heel to the ankle, knees, hips
and back causing a plethora of common running injuries.
[0009] Barefoot locomotion such as running, hiking and walking
forces the athlete to move in a natural evolutionary ergonomically
efficient way that puts less stress on the joints by landing on the
forefoot or midfoot. By absorbing impact forces with the
springiness of slightly bent knees, short stride and rapid foot
turnover, barefoot locomotion develops muscle strength in the feet,
legs and hips which is healthier for feet and reduces chronic
repetitive stress injuries as typically occurs during running and
the like. However, barefoot locomotion has all the risks and
limitations associated with being barefoot outdoors in the modern
society like but not limited to sanitation, puncture and abrasion
wounds. For example when traveling barefoot outside a person has no
insulation or protective barrier to shield bare feet from exposure
to broken glass, metal shards, various debris and other modern
barefoot hazards. This results most notably in lacerations,
abrasion burns, blisters and bleeding. The overall cleanliness of a
person's feet is dramatically impacted when no foot protection is
worn. Lastly, barefoot people typically are not permitted in stores
or allowed in attendance to most social events.
[0010] Attempts to produce a running shoe or sandal that has all
the benefits of barefoot locomotion have been numerous and
unsatisfactory. Every major shoe company and a plethora of minor
shoe companies have shoe models that are claimed to mimic barefoot
running, hiking, walking and the like locomotion. For example in
U.S. Pat. Nos. D658,868 S and KR 933,683 includes a sole insert and
a thick rubber bottom layer. These two layers create soles that are
too thick to properly simulate barefoot running, and negatively
affect the user's balance, posture, and running style. Further
negatives for these products include extra weight and difficulty
keeping them sanitary, as well as providing artificial arch support
which impair the foot's arches from performing its natural spring
function. Other sports sandals and shoes like U.S. Pat. No.
0,116,840 have a cord lock adjustment in the back of the sandal
that cause rubbing and abrading on the Achilles tendon. Barefoot
shoes, barefoot sandals, minimalist shoes, huaraches and the like
suffer from a combination of limitations and disadvantages listed:
[0011] (a) The use of padded soling material on their sports shoes
and sandals permits the wearer to heel strike cause joint and feet
injuries. [0012] (b) As the padding and shoe structures break down
the shoe magnifies and accelerates the frequencies of foot and
joint injuries. [0013] (c) The use of synthetic materials that do
not conform to the contours of the athlete's feet restrict the
natural motion of the feet. [0014] (d) Their shoe construction and
method of attaching the shoe to the foot utilize straps, cloth,
canvas, synthetic soles, and the like structures that confine,
constrain and control the feet in an unnatural manner. [0015] (e)
By enclosing the wearer's foot in the confining structures of
typical athletic shoes the user needs to clean the interiors for
comfort, sanitation, and the elimination of unpleasant odors.
[0016] (f). Wearing their shoes cause the users to incur an
additional expense of purchasing sweat and moisture absorbing socks
that make the feet hot and uncomfortable. [0017] (g) Socks are
needed to protect the wearer's feet from the confining, abrading,
and blistering caused by the foot making unprotected contact with
their shoes. [0018] (h) The confining nature of their shoes
deprives the wearer of the necessary sensory information from the
feet to adjust the users stride which reduce injuries. [0019] (i)
The cast like structures of their shoes over support the foot
structures weaken the feet. [0020] (j) Lack of a sole repair method
increases the shoe cost and reduces the useful life of their shoes
necessitating purchasing a complete shoe replacement just when the
shoe finally becomes comfortable but the sole is worn out. [0021]
(k) Their shoes deprive the wearer the benefit of the airy barefoot
locomotion feeling of freedom.
SUMMARY
[0022] In accordance with one embodiment a sports sandal having a
sole that conforms to the user's foot attached with a singular
adjustment attachment cord, and having an anti-slip heel cushion
positioned on the Achilles tendon, and having an adjustable cord
lock, and with a replaceable anti-skid overlay attached to the
underside of the sole.
Advantages
[0023] Accordingly several advantages of one or more aspects are as
follows: to provide a sports sandal that provides protection from
barefoot hazards and provides sanitation. It permits the foot arch
structures to move naturally as in barefoot locomotion, conforms to
the natural contours of the human foot, and has a sole that molds
to the wearers arch after the break in period forms a natural arch
support, is open aired, comfortable, speedy to adjusted with a cord
lock. It has a singular adjustment attachment cord system,
comfortable cord suspension system that centers the foot on the
sole, has an anti-slip heel cushion, has less than two degrees of
co-planarity of the sole, and is light weight. The anti-skid slip
resistant coating improves foot agility and safety. Other
advantages or one or more aspects will be apparent from a
consideration of the drawings and ensuing description.

and a spring when squeezed together, tension is released and the
cord lock can move freely up and down the cord, when released, the
tension is engaged and the cord lock stays in place. Next the
attachment cord 3 passes through the circular or specifically
shaped hole 4 that is located on the lateral side of the foot
forward of the ankle towards the distal side of the foot through
sole 1, that was punched or cut to permit the snug restricted
passing of attachment cord 3 through sole 1. Attachment cord 3 is
then threaded through anti-slip heel cushion 10 composed of soft
rubber latex tubing, silicone tubing or the like through which
attachment cord 3 is positioned on the Achilles tendon to secure
the posterior end of the sole 1 to the foot. Then attachment cord 3
starting at the planter side of sole 1 passes through the circular
or specifically shaped hole 5 that is located on the medial side of
the foot forward of the ankle towards the distal side of the foot
through sole 1, that was punched or cut to permit the snug passing
of attachment cord 3 through sole 1. Attachment cord 3 next passes
back through plastic cord lock 8 to secure sole 1. A typical over
hand knot 11 is tied in attachment cord 3 to keep the cord lock 8
from slipping off the attachment cord 3 immobilizes and prevents
slippage of cord lock 8. Cord 3 is formed into aglet 12 terminuses
by separating and trimming less than half of the core yarns 2.5
inches (6.35 cm) thermally liquefied and cooled globular mass of
the outer sheath and the remaining yarns of cord 3 then are tapered
into an aglet terminus 12.
[0060] Illustrated in FIG. 2 (bottom view) beginning on sole 1, at
hole 2 attachment cord 3 is threaded through hole 2 located by the
great toe. Views of cord 3 threaded through hole 4 and hole 5 is
shown. The outer braded sheath 6 of the splayed end terminus of
attachment cord 3 is thermally-liquefied and solidified into an
irregular globular ring that fits snugly around hole 2 at the
planter side of sole 1. The seven or more nylon yarns are splayed
on sole 1 plantar in a specific three way pattern such that they
pass under the great toe, between the great and second toe and
under the remaining toes on the planter side of sole 1. The strands
are affixed with an adhesive such as 3M Scotch-Weld or the like
beneath the slip resistant anti-skid overlay 9 and planter side of
sole 1. A layer of slip resistance anti-skid overlay material such
as 3M Safety-Walk.TM. consisting of a large abrasive particles
bonded by a durable polymer on a plastic film with the reverse side
covered with a pressure sensitive adhesive or the like, or Shoe
Goo.RTM. which is a pliable adhesive sealer primarily used to
repair athletic shoes, or the like, trimmed or applied to follow
the outline of the foot above with notched setbacks for the main
medial foot arch and the lateral hole 4, which is centered and
applied to the planter side of the sole 1 to cover the typical wear
points.
[0061] Illustrated by FIG. 3 (cross section of sole 1 at the distal
end) is sole 1, the attachment cord 3 between the great toe 7 and
the second toe. The great toe 7 is shown in the normal position.
Sole 1 is composed of a single layer consisting of leather or the
like material. Layer of slip resistance anti-skid overlay material
such as 3M Safety-Walk.TM. consisting of a large abrasive particles
bonded by a durable polymer on a plastic film with the reverse side
covered with a pressure sensitive adhesive or the like, or Shoe
Goo.RTM. which is a pliable adhesive sealer, or the like, trimmed
or applied to follow the outline of the foot above with notched
setbacks for the main medial foot arch and the lateral hole 4,
which is centered and applied to the planter side of the sole 1 to
cover the typical wear points.
FIGS. 1-4--A Second Embodiment
[0062] A second embodiment includes all the elements in FIGS. 1, 2,
and 3 listed and discussed above. Plus the additional element
included in FIG. 4 (cross section of the distal end with a midsole)
is illustrated. In addition to all the items, methods and process
listed in embodiment one a midsole element 13 composed of EVA foam
or like material that decreases in elasticity as it conforms to the
contours of the wearer's foot plantar is sandwiched between the
outer sole 1 layers comprised of leather or like. The midsole shape
is the same length and width as that of the sole 1 but with cut
outs that match the medial and lateral outline of the skid
resistant anti-slip overlay 9 which permits the sole to flex at the
arch near hole 5 and near attachment point near hole 4.
FIGS. 1-5--A Third Embodiment
[0063] A third embodiment includes everything in embodiment one,
FIGS. 1, 2, and 3 listed and discussed above, and the mid sole
element discussed in embodiment two, FIG. 4. The new elements are
listed in FIG. 5 (cross section of the distal end of the sports
sandal of FIG. 1 mid sole element FIG. 4, spike receptacle and
typical spike) shows the midsole 13 identified in embodiment two. A
spike receptacle 14 for cleats or spikes is attached to sole 1 by
cutting a hole, securing by means of rivets, screws, nails, glue or
such, arranged in typical patterns common in golf, running, hiking
shoes, and the like, composed of metal, nylon, plastic or the like,
with female threads designed to receive threaded cleat or spike 15
used to improve traction on golf course, artificial track, mud, ice
and the like may be comprised of metal, plastic, nylon or the like,
typical for golf, running, climbing and such.
Alternative Embodiments
[0064] There are various other possibilities with regard to
constructing alternative embodiments such as FIGS. 3, 4, and 5 by
varying the number of layers of the mid sole, or number of layers
of the single sole. In FIG. 1 the anti-slip tread could be composed
of a type of industrial coating that has similar wear properties,
or the anti-slip heel cushion could be formulated in a different
lengths and thicknesses.
ADVANTAGES
[0065] From the descriptions above, a number of advantages of some
embodiments of my sports sandal with a singular adjustment
attachment cord become evident: [0066] (a) Using thin 8-10 ounce
(3.5 to 4.0 mm) natural leather or soling material with leather
characteristics on the sport sandal encourages the wearer to use
good barefoot form of midfoot or forefoot striking which reduces
joint and feet injuries. [0067] (b) Reduced frequencies of foot and
joint injuries by using little or no padding and few shoe
structures to break down and accelerate injuries. [0068] (c) Uses
natural leather or a less rigid soling material that conforms and
supports the natural motion of the athlete's feet. [0069] (d) Sport
shoe construction and method of attaching the shoe to the foot that
does not utilize straps, cloth, canvas, synthetic soles, and the
like structures that confine, constrain and control the wearer's
feet in an unnatural manner. [0070] (e) Improves sanitation by
exposing the wearer's feet to open air, sunshine and non-confining
shoe structures. [0071] (f) Eliminates the user's need to purchase
sweat absorbing socks for athletic shoe comfort. [0072] (g)
Eliminates the need for socks to protect the wearer's feet from
abrasions, blisters, and foot sores caused by the wearer's foot
making contact with the interior of typical athletic shoes. [0073]
(h) Wearer's feet provide immediate uncomfortable sensory feedback
reducing injuries by causing athletes to adjust their stride thus
reduce bone jarring heel striking pounding. [0074] (i) Eliminates
shoes with cast like structures that over support the foot and
weaken the feet. [0075] (j) Provides a sole repair method that
reduces sports shoe cost and increases the useful life of the
sports sandal by reduces the necessity of complete replacement of
the shoes just when the shoe gets comfortable and the sole wears
out, [0076] (k) Easy tread replacement accomplished by replacing
the layer of slip resistance anti-skid overlay material with a new
tread or with a pliable adhesive sealer typically used to repair
athletic shoes which restores planter sole surface to near new
condition and function, [0077] (l) Simple adjustment procedures of
pulling the adjustment cord through the side holes then tightening
the cord lock until a comfortable fit is attained, [0078] (m) The
sports sandal with a singular adjustment attachment cord gives the
wearer the benefit of an airy feeling of freedom similar to
barefoot mobility with sanitation and puncture protection.
CONCLUSION, RAMIFICATIONS, SCOPE
[0079] Accordingly, the reader will see that the sports sandal with
a singular adjustment attachment cord of various embodiments can be
used to provide the user with the benefits of puncture protection
and sanitation during near barefoot locomotion that: [0080]
encourages the wearer to use the good barefoot midfoot or forefoot
striking form by providing immediate sensory feedback information;
[0081] encourages the wearer's to adjust his stride to eliminate
pounding from heel striking which reduces joint and feet injuries;
[0082] by using materials that conform to the contours of the
athlete's feet the sport sandal eliminates shoes with cast like
structures that over support the foot and weaken the feet; [0083]
by attaching the sole to the foot without utilizing straps, cloth,
canvas, and the like structures the wearer's feet are not an
confine, constrain and control in an unnatural manner; [0084]
provides good sanitation by exposing the wearer's feet to the open
air and sunshine and not the confining structures of athletic
shoes; [0085] eliminates the additional expense of purchasing sweat
absorbing socks to protect the wearer's feet from abrading caused
by the foot making contact with the interior of typical athletic
shoes; [0086] provides sole repair methods that reduces sports shoe
cost and increases the useful life to the sports sandal by reduces
the necessity of completely replacing the shoes when the shoe
begins to show excessive wear; [0087] has a simple adjustment
procedures whereby pulling the adjustment cord through the side
holes, then tightening the cord lock until a comfortable fit is
attained, and using the overhand knot to secure the cord lock on an
attachment cord; [0088] has a sandal suspension system that forms a
structure with the attachment cord as it tightens the moldable sole
against the main foot arch during the break in period resulting in
natural arch support; [0089] has a singular adjustment attachment
cord that provides the wearer the benefit of the airy feeling of
freedom with barefoot like mobility with sanitation and puncture
protection.
[0090] Although the description above contains much specificity,
these should not be construed as limiting the scope of the
embodiments but as merely providing illustrations of some of
several embodiments. For example, it is contemplated that the
present invention essentially provides a sole, singular attachment
cord, anti-slip Achilles heel cushion, and a cord lock, and a slip
resistant treaded sports sandal as of FIGS. 1-5 clearly
demonstrates that is suitable for various types of foot locomotion,
mobility, activities, etc.
[0091] Thus the scope of the embodiments should be determined by
the appended claims and their legal equivalents, rather than by the
examples given.
