ABSTRACT:
A prosthetic foot which has an ankle member adapted for mounting on the leg of a user and provided with a forwardly disposed wedging surface; a toe member provided with a wedging surface facing the wedging surface of the ankle member; a resilient sheet extended longitudinally of the foot beneath the members, connecting them for relative pivotal movement as the sheet flexes; a wedge disposed between the surfaces; and a screw mounted on the sheet and engaging the wedge so that rotation of the screw adjustably positions the wedge between the surfaces pivoting the members selectively to arch and to flatten the interconnected members to adapt the foot for use with shoes having heels of different heights.
