ABSTRACT:
A prosthetic foot includes a pair of elongated forefoot leaf springs with proximal ends coupled to an attachment member and extending in an arc to distal ends with the forefoot leaf springs being oriented with one over another. The pair of forefoot leaf springs has different lengths and is coupled to one another at the proximal and distal ends defining an open, uninterrupted gap between the forefoot leaf springs. A pair of hinge connections can be disposed each at a different one of the proximal and distal ends of the pair of elongated forefoot leaf springs. The pair of forefoot leaf springs together has a non-linear force deflection under loading during gait.
