Prosthetic foot with reinforcing member

A prosthetic foot comprising:

• at least two resilient forefoot members having base ends coupled near an attachment location and extending forward to toe ends at a toe location, the at least two forefoot members having a range of motion with multiple stages of advancement including at least a normal range and an extreme range and having a resistance response to an applied force;
• at least one resilient heel member having a base end coupled to at least one of the at least two resilient forefoot members and extending rearward to a heel end at a heel location, the at least one heel member having a range of motion including a normal range and an extreme range and having a resistance response to an applied force;
• and
• at least one resilient reinforcement member having a base section coupled to at least one of the at least two forefoot members and extending to a free section proximal either the toe location or heel location and spaced above the at least two resilient forefoot members or heel members, the free section being disposed within the extreme range of motion of any of the at least two forefoot members or the at least one heel member and freely movable with respect to any of the at least two forefoot members or the at least one heel member, the reinforcement member having a range of motion within the extreme range of motion of any of the at least two forefoot members or the at least one heel member, such that the reinforcement member influences the range of motion and resistance response of any of the at least two forefoot members or the at least one heel member.
