Abstract

A prosthetic foot (70) incorporates a foot keel (71) and a calf shank (72) connected to the foot keel to form an ankle joint area of the prosthetic foot. The foot keel has forefoot and hindfoot portions and an upwardly arched midfoot portion extending between the forefoot and midfoot portions. The calf shank includes a downward convexly curved lower end which is adjustably attached at a portion thereof to the foot keel by way of a releasable fastener arrangement which includes a coupling element (73) intermediate the calf shank and foot keel. The coupling element includes a resilient material forming a joint permitting subtalar joint-like motion of the prosthetic foot in gait.
