Abstract
A foot prosthesis and multi-step process for making same, has an upper main member and a sole member as dual segments of the prosthesis and arrangements for removably securing the prosthesis to a stump socket. The upper member has a U-shaped shank strut and flat ankle transition zone and an anterior toe section. The sole member has a plantar toe section and heel section. The invention is specially design to accommodate construction from fiberglass composite materials although the design will accommodate construction from other composite materials or even other materials that are not of the composite type. The process for making the foot prosthesis comprises the steps of forming the two segments. Then the formed segments are bonded together using a compatible resilient elastomer material, such as a high elongation, polyurethane elastomer, a silicone adhesive, or fiber reinforced versions of such elastomers.
