An improved foot prosthesis is disclosed which is durable in performance and inexpensive to manufacture, yet effective in accurately duplicating the feel and dynamic performance characteristics of the natural human foot. The prosthesis incorporates a single composite member having a forefoot portion beneath which is molded a unitary elastomeric sole that projects rearwardly from the composite member to define a heel. The elastomeric sole also projects laterally from the composite member so as to provide a degree of lateral stability that matches the inversion/eversion resistance of the normal human foot. In addition, a separate height adjuster and/or stiffness adjuster can be removably attached to the underside of the elastomeric sole, to enable the user to selectively adjust the prosthesis' heel height and/or stiffness.
