Abstract
A prosthetic foot comprises an elongated, substantially two-dimensional, resilient toe member, an elongated, substantially two-dimensional heel member, and a substantially rigid carrier member. One end of each of the toe and heel members is independently connected to the carrier member. The toe and heel spring members can be selected independently so as to provide the wearer with personalized characteristics and responses at heel-strike, foot-flat, and toe-off.
