Prosthetic foot with enhanced heel control

A resilient prosthetic foot keel comprising:

• (a) a unitary spatula member, defining an elongated, lower, fore and aft extending forefoot member, an upper fore and aft extending rear member, and a generally wavy intermediate member integrally transversely joining said forefoot and rear members in an axially offset fashion;
• (b) a generally arcuate unitary heel member, defining a flat top heel part, a bottom heel part, and an intermediate heel part transversely integrally interconnecting said top and bottom heel parts;
• and
• (c) attachment means, fixedly interconnecting said top heel part to said spatula rear member;
• wherein a generally open pocket is defined by said heel member and by said spatula intermediate and rear members, said pocket opening both rearwardly of the foot keel and laterally outwardly thereof on the side opposite said intermediate heel part, and wherein the shape of said open pocket is resiliently deformable responsively to the cyclical loads sustained by the spatula forefoot member and bottom heel part during the wearer's gait.
