Abstract
A prosthetic foot having a spring assembly with an anterior and posterior component, a snubber for limiting the movement of the spring assembly during assembly, and anterior and posterior shock absorbers provided between the components of the spring assembly and snubber. The arrangement of the posterior shock absorber, the spring assembly, and the snubber is such that ambulation results in the generation of a compressive force in the posterior shock absorber during a heel-strike phase and tensile force in the posterior shock absorber during a toe-off phase.
