ZOLA FZYE Kswomcx FOOT GUARD 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 seam, 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 threefoutths 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 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 wearers foot 13 in such a manner so as to allow the wearers 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.
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 users 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 nonirritating securement means for said footwear to the users 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 wearers 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 accord ng 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.
