Claims
What I claim is:
1. Footwear, comprising in combination, a structure of seamless
foam rubber, a sole portion, and instep portion, and a heel portion
carried by said seamless structure providing form fitting means for
a user's feet when used in pairs, and straps carried by said
structure for adjustably securing said footwear to the feet of said
wearer, said seamless foam rubber structure comprising said
footwear including an opening at a forward end in order for the
toes of said wearer to extend there for maximum ventilation and
comfort, the sole portion of said structure being straight and flat
while providing a maximum of circulation through elliptical
openings there through, said openings providing a circulation of
air to the sole portion of said wearers feet.
2. The combination according to claim 1, wherein said heel portion
extends from said sole portion, and the side portions of said
structure extends forwardly, thus forming said straps which are
adjustable and overlapping, the ends of said straps having mating
velcro fasteners to provide maximum comfort and nonirrating
securement means for said footwear to the user's feet, the forward
portion of said structure providing incasement means for the lower
portion of the instep and the forward portion of said sole of the
wearer's foot, the strap when secured by said fasteners in
combination with the forward portion of said structure defining an
opening in the upper portion of said instep and providing maximum
air circulation forwardly of the ankle of said wearer.
3. The combination according to claim 2, wherein the heel portion
of said foam rubber structure is provided with a pair of oppositely
and aligned openings rearwardly and slightly below the ankle bone
of the wearer, said openings being circular and providing air
circulation in the heel and ankle area.
4. Said footwear being of seamless and fastenerless structure
provides maximum comfort to the wearer by being continuously
resilient to the contour of the foot placed therein and said
seamless foam rubber structure provides a means for air to reach
all of the areas said foot contacts by said structure being
inherently porous.
Description
This invention relates to footwear, and more particularly to
aerated footwear.
It is therefore the main purpose of this invention to provide a
foot guard which will be used in pairs and will provide a maximum
of comfort for the feet of the wearer.
Another object of this invention is to provide a foot guard which
will have no seams, buttons, zippers, grippers, or other devices in
order to prevent any pressure on any area of a foot of the user and
the device when used in pairs may be constructed in various
sizes.
A further object of the invention is to provide a foot guard which
will be constructed of seamless foam rubber or the like which will
be of a thickness of one-fourth of an inch to three-fourths of an
inch, the thicker portions being over the ankle bones, heels and
the sides of the feet and toes, the thinner areas being the sole
straps, on the top portion of the foot.
A still further object of the present invention is to provide a
device of the type described which will have a sole that is not
curved to fit the arches of the foot, the sole being straight and
flat to offer a maximum of circulation to the elliptical shaped
openings over the bottom of the foot.
Other objects of the invention are to provide a foot guard which is
simple in design, inexpensive to manufacture, rugged in
construction, easy to use and efficient in operation.
These and other objects will be readily evident upon a study of the
following specification and the accompanying drawing wherein:
FIG. 1 is a side view of one of the foot guards shown in elevation
and partly broken away;
FIG. 2 is a bottom plan view of FIG. 1; and
FIG. 3 is a fragmentary view similar to FIG. 1, but showing the
straps unfastened and the foot removed therefrom.
According to this invention, a foot guard 10 is shown to include a
sole portion 11 having a pair of spaced-apart elliptical openings
12 providing for a maximum of circulation of air. The foot guard 10
receives the wearer's foot 13 in such a manner so as to allow the
wearer's toes 14 to extend outward from the open end 15 and the
main body portion 16 includes a pair of openings 17 on either side
which are positioned slightly below and rearward of the ankle bone
of the foot 13, the openings 17 providing for air circulation in
the aforementioned area of foot 13. The upper extremity of main
body portion 16 includes a pair of straps 18 which are provided
with mating velcro fasteners 19 enabling guard 10 to be held to
foot 13 without any pressure being applied thereto, the straps 18
being overlapped at various points to fit the wearer.
