ABSTRACT:
A dynamic prosthetic foot having multiple load points and an anterior/posterior pair of upper sections includes a sole and an upper member. A heel end of the upper member has a gradual ninety degree bend formed in so that it is normal to the sole. An elongate longitudinally-extending slot divides the heel end of the upper member into a lateral, anterior pylon support and a medial, posterior pylon support and further divides the upper member into a lateral upper section and a medial upper section. The lateral, anterior pylon support is thicker than the medial, posterior pylon support and the lateral upper member section is thicker than the medial upper section so that forces applied to the lateral, anterior and medial, posterior pylons are transferred to a greater extent to the medial, posterior pylon. In a second embodiment, elongate pylons supplant the pylon supports.
