ABSTRACT:
A prosthetic foot is characterized by an attachment section and plurality of curvilinear foot portions extending downwardly from the attachment section to contact a supporting surface. The portions are capable of movement independent from one another. Preferably, the plurality of foot portions is fabricated by dividing a forefoot portion and a heel portion demountably attached thereto. Such division may be achieved by the provision of a slot in said forefoot and heel portions. A strap or similar expedient is provided to limit the movement of the foot portions relative to each other.
