Abstract
A foot prosthesis comprised of a single monolithic elongated composite member having a semi-flexible shank strut section, an ankle section, a forefoot section, and a toe section. One end of the shank strut section is connected to a socket which is adapted to receive an amputated leg stump. The other end smoothly curves downwardly, or downwardly and rearwardly, before curving forwardly of the shank strut section to the toe section. The invention is specially designed to accommodate lower limb amputee athletes participating in field and track events.

A foot and leg prosthesis for use by an amputee having a natural limb forefoot length comprising an elongated monolithic composite member having a semi-flexible shank strut section, an arcuate ankle section, a forefoot section, and a toe section;
- one end of said shank strut section being connected to a socket adapted to receive an amputated leg stump, the other end extending straight to said ankle section, said member beginning said ankle section by smoothly curving rearwardly from the straightly extended portion of the shank strut section and then forwardly through said ankle section, said forefoot section and said toe section.
A foot and leg prosthesis for use by an amputee having a natural limb forefoot length comprising an elongated monolithic composite member having a semi-flexible shank strut section, an ankle section of greater thickness than that of the shank strut and forefoot sections, a forefoot section of longer length than an amputee's natural forefoot length, and a toe section;
- one end of said shank strut section being connected to a socket adapted to receive an amputated leg stump, the other end smoothly curving downwardly and then forwardly of the shank strut section through the ankle section, forefoot section and to said toe section.
