ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a post-operation shoe, more particularly to a post-operation shoe for elevating and supporting a post-operative or otherwise traumatized foot portion in order to remove pressure from the foot portion when the foot portion is the forefoot or the heel.
2. Description of the Related Art
When surgical operations have been done to a foot portion or when a foot portion is otherwise traumatized, the patient feels discomfort while walking due to the pressure applied on the traumatized foot portion. It is thus desirable to elevate the traumatized foot portion during walking so as to remove pressure therefrom and sooth the pain in the traumatized foot portion. U.S. Pat. No. 5,138,777 discloses a post-operative shoe which includes an upper assembly secured to a sole assembly, and a wedge undersole of triangular shape. The wedge undersole is integrated to a bottom surface of a midsole of the sole assembly, and ensures the top surface of the midsole to extend upwardly and forwardly in a direction toward the toe region of the shoe. This type of post-operative shoe help to relieve pressure on the forefoot, and is only suitable when the traumatized portion is at the forefoot.
It is thus desirable to provide a post-operation shoe which can be used for a foot which is traumatized at either the forefoot or the heel.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a post-operation shoe for a foot which is traumatized at either the forefoot or the heel.
According to a first aspect of the present invention, a post-operation shoe includes a sole, a wedge member, an upper and hook-and-loop fastener means. The sole includes an outsole member and amidsole member, the outsole member having first and second end portions which are opposite to each other in a longitudinal direction, and an intermediate portion between the first and second end portions, the midsole overlying and releaseably connected to the outsole member. The wedge member is formed integrally with a bottom side of the outsole member at the intermediate portion, and has a flat bottom end face adapted 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. The upper includes an instep strap, an ankle strap, and left and right end portions extending downward from the instep strap and inserted between the midsole and outsole members. 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.
According to a second aspect of the present invention, a post-operation shoe includes an elongate outsole member, a wedge member, an upper, a midsole member and a releasable connector. The outsole member has first and second end portions which are opposite to each other in a longitudinal direction, and an intermediate portion between the first and second end portions. The wedge member is secured to a bottom side of the outsole member at the intermediate portion, and has a flat bottom end face adapted 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. The upper has an instep strap and an ankle strap. The midsole member is connected to the upper, and overlies the outsole member. The midsole has a heel portion beneath the ankle strap. The releasable connector is disposed on and interconnects the midsole and outsole members. The midsole member is detachable from the outsole member to change from a position in which the heel portion is located immediately above the first end portion, to another position in which the heel portion is located immediately above the second end portion, and vice versa.
