Abstract
A prosthetic foot is comprised of a springy internal frame embedded in a resilient foot-shaped outer body. The frame is in the shape of a modified trapezoid, wherein the shorter top member and the longer bottom member are connected by a generally vertical back member, and a substantially oblique front member. A toe member extends from the bottom member into a toe portion of the outer body. A solid carbon fiber layer is embedded in the frame for strength and elasticity. A break is provided between the lower end of the front member and the bottom member to enable the toe portion of the foot to flex laterally. A flexible cord is connected across the break to prevent the front and bottom portions of the frame from separating when the foot kicks an obstacle.
