ABSTRACT:
A prosthetic foot characterized by a foot portion having an ankle portion demountably and interchangeably connected thereto. The foot portion and ankle portion are fabricated from polymer impregnated and encapsulated laminates, including such laminates as carbon fibers and/or fiberglass or synthetic fibers such as Kevlar. The demountable connection of the ankle portion permits interchangeability of ankle and foot portions to match the weight, stride and activity schedule of the wearer utilizing the prosthetic foot. Auxiliary ankle members and wedge blocks between the foot portion and the ankle portion provide additional adjustability. A split sleeve is provided for assembling the various components.
