Abstract: A prosthetic foot including a ground-engaging base in the form of a generally planar and resiliently flexible foot bed which extends between two or more platforms to form one or more flexible hinges therebetween. The platforms include a toe platform, a mid-section platform and a heel platform. A support shank is disposed above the platforms so as to be generally positioned above an ankle area of the foot. A first spring extends from the toe platform to the support shank. A second spring extends from the support shank to the mid-section platform. A third spring extends from the support shank to the heel platform. Typically, the springs are curvilinear springs.
