ABSTRACT:
In a prosthetic foot constructed to store strain energy as the foot reacts to the load of the amputee's body during walking, running, jumping, etc., and then to release the stored energy to create foot lift and thrust which complements the user's natural stride, a monolithic cantilever beam made of a hardened polymer is provided as the keel of the foot with an ankle attachment fitting for connection to a standard upper prosthesis. A flexible foamed polymer is molded about the keel, in the shape of a natural foot, to transfer horizontal loads to the keel and to serve as a cosmetic cover.
