Abstract
A prosthetic foot (70) incorporates a foot keel (77) 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. The upper end of the calf shank is movable longitudinally of the foot keel in response to force loading and unloading the calf shank during use of the prosthetic foot. A device (71) connected between the ends of the calf shank limits the extent of the motion of the upper end of the calf shank relative to the lower end and foot keel. The upper end of the calf shank can include an alignment coupler device (92) thereon having adjustable slide mechanisms to adjust the medial/lateral and anterior/posterior position of the calf shank relative to a supporting structure on the leg of the person using the prosthetic foot.
