Abstract

A post-operation shoe includes an outsole member having first and second end portions, an intermediate portion, an integral wedge member formed at a bottom side of the outsole member at the intermediate portion to be in contact with the ground. The wedge member is tapered in the longitudinal direction so that the second end portion is disposed higher than the first end portion. An upper includes an instep strap, an ankle strap, and left and right end portions extending downward from the instep strap and inserted between the outsole member and a midsole member which overlies and detachably connects with the outsole member via screws. The hook-and-loop fastener means is disposed on the left and right end portions and on one of the midsole and outsole members to releasably mount the upper on the sole, whereby the upper can be positioned to the sole interchangeably between a first position in which the ankle strap is located adjacent to the first end portion, and a second position in which the ankle strap is located adjacent to the second end portion.

Claims

1. A post-operation shoe comprising:

a sole including an outsole member and a midsole member, said outsole member having first and second end portions which are opposite to each other in a longitudinal direction, and an intermediate portion between said first and second end portions, said midsole overlying and releaseably connected to said outsole member;

a wedge member formed integrally with a bottom side of said outsole member at said intermediate portion, and having a flat bottom end face adapted to be in contact with the ground, said wedge member being tapered in said longitudinal direction so that said second end portion is disposed higher than said first end portion;

an upper including an instep strap, an ankle strap, and left and right end portions extending downward from said instep strap and inserted between said midsole and outsole members; and

hook-and-loop fastener means being disposed on said left and right end portions and on one of said midsole and outsole members to releasably mount said upper on said sole, whereby said upper can be positioned to said sole interchangeably between a first position in which said ankle strap is located adjacent to said first end portion, and a second position in which said ankle strap is located adjacent to said second end portion.

2. The post-operation shoe as claimed in claim 1, wherein said bottom side of said midsole member is further provided with scale marks which serve as reference for adjustment of the size of a space confined by said upper and said sole in order to fit the size of a human foot.

3. The post-operation shoe as claimed in claim 2, further comprising screws for fastening detachably said midsole member and said outsole member.

4. The post-operation shoe as claimed in claim 3, wherein said sole has a line of symmetry which passes through said intermediate portion and which is transverse to the longitudinal direction.

5. The post-operation shoe as claimed in claim 1, wherein said hook-and-loop fastener means is disposed on a bottom side of said midsole member.
