Abstract: A sock lining layer corresponding to the shape of a shoe is secured to one side of a foam layer of substantially the same size and shape. A backer layer is secured to the other side of the foam layer. The periphery of said layers are secured together. Slippage control between the sock lining and the foam layer is attained by stitching in the form of a closed loop wholly disposed at the location adapted to support a ball of a foot. The loop stitching has two extensions each extending from one end of the loop to the periphery of said layers at a location between the heel end of the layers and said one end of said loop.

Abstract: A shoe, particularly a sport shoe, has a sole with a shallow recess therein that is closed by a lining impervious to air. The upper of the shoe also has air chambers therein, in surrounding relationship to the heel, these latter chambers also communicating with the air chamber of the sole. A crescent-shaped piece at the rear of the upper protects the Achilles' tendon of the wearer and is hollow and flexible and communicates with the air chamber in the shoe sole. As a result, the air chambers can deform substantially so as to absorb shock and protect the rear of the foot of the wearer, at the same time that the pressure in the various chambers does not greatly change.

Abstract: A sole supporting and cushioning member for footwear controlling the movement of foot/leg muscles in the form of a removable, preferably disposable sole shock absorber that is adapted to afford an elastic or cushioned bearing for the wearer's feet which comprises a pliable coil filled with an elastomeric material to resiliently flex with the movement of the sole of the foot.

Abstract: A construction and method of forming shoe inserts in order to support the arch of the entire foot, in which a flexible container is filled with a formable material that is capable of curing at about room temperature to form an elastomeric material, the container is placed inside the shoe beneath the foot, and pressure is maintained on the foot while the formable material sets and hardens.The formable material may be provided by means of a catalyst-filled inner container with frangible walls which can be ruptured by applying pressure to the outer container, thereby to admix the catalyst with a curable elastomeric material which fills the rest of the outer container's volume.

Abstract: An orthopedic shoe including: a flat, level sole having a peripheral shape corresponding to that of the bottom plane of a foot and whose toe portion is very broad and of substantially constant width, whose central, metatarsal portion curves rapidly inwardly to a narrow neck connecting the toe portion with a heel portion, the ratio of the widths of the toe and heel portions being approximately 100 to 60, and the ratio of the toe portion to the neck of the central portion being approximately 100 to 40, the inner sole being formed in a plurality of layers at least of one of which is of compressible material capable of permanently conforming to the shape of the bottom of a foot under pressure of wearing; combined with an upper having a counter, a vamp and a toe portion, the vamp including a pair of widely spaced forwardly projecting flaps each including a row of eyelets and extending along the upper parts of the sides of the foot, the toe portion having a wide rearwardly extending tongue for covering the metatars
