Abstract A shoe construction primarily intended as a prosthetic device to be worn by a patient who has sustained an injury or operation on the ball of the foot or the forward portion of the foot to elevate same from the floor while walking and to cushion and support the foot while walking, or while the patient is in prone position. The shoe evenly distributes the weight of the wearer on the arch and heel of the foot, enabling the wearer to walk comfortably after surgery without applying pressure to the ball of the foot. It consists of an open ended boot in which a liner conformed to the shape of the foot is detachably inserted and held in place about the foot. The boot may be made to accommodate different sizes of feet into which liners may be inserted and detachably secured so that same may be reused by patients having different sizes and shapes of feet. The liner is made by a unique method to form a unitary liner of foam plastic encased with a thin layer of polyvinyl chloride (PVC) or like material with the lower surface on the liner covered with impervious nylon fabric held in place by friction discs provided thereon.
