Abstract

A shoe of use on a post-operative or otherwise traumatized foot includes a sole assembly having a outer sole, a shock absorbing midsole and an inner sole conforming generally to the contour of the sole of the foot, the sole assembly having a limited degree of flexibility, and an upper assembly including an outer wall of a flexible mesh material and a lining of a soft, conformable material, adjustable straps connecting the opposite sides of the forward portion of the upper assembly. Preferably, the sole assembly is tapered, being of greatest thickness in the heel region; the heel portion of the upper is angled forwardly and upwardly; and one of the forward portions of the upper is of greater length than the other to protectively cover the dorsal aspect of the foot.

Claims

1. A surgical shoe adapted for use on a post-operative or otherwise traumatized foot comprising:

a sole assembly including an inner sole conforming generally to the plantar aspect of the foot, a midsole of an impact absorbing material, said midsole having its greatest thickness in the heel region and tapering downwardly toward the toe region, and an outer sole, said sole assembly having a degree of flexibility similar to that of a conventional running shoe sole assembly; and

an upper assembly secured to said sole assembly and adapted to surround the heel, sides and dorsal portions of the foot while leaving the toe region open, the heel region of said upper assembly being angled forwardly and upwardly from the sole assembly, the forward portions of said upper assembly being divided into left and right flaps one of which is of greater length than the other, is adapted to cover the dorsal region of the foot, and underly said other of said flaps, and strap means for interconnecting the outerface portions of said left and right flaps.

2. The surgical shoe of claim 1 further including a molded fiberglass insert adapted to closely conform to the contour of a portion of the foot and to be interposed between the foot and said inner sole.

3. The surgical shoe of claim 1 wherein said upper assembly includes an outer wall of a woven nylon mesh material and a lining of a conformable plastic foam material.

4. The surgical shoe of claim 3 wherein said lining is bonded to the inner face of said outer wall.

5. The surgical shoe of claim 1 wherein said midsole is formed of ethylene-vinyl, acetate copolymer.
