Abstract
A prosthetic foot includes a spring component and a sole component. The spring component comprises two or more stacked beam elements, each beam element including, along the length of the respective beam element, a first portion and a second portion, and the second portion of the beam element includes an extent with a length-varying width. The respective beam elements are fixed to each other and to the sole component proximate the heel portion of the sole component or the toe portion of the sole component at the first portions of the respective beam elements to form a fixed end of a cantilevered composite beam. The second portions of the respective beam elements are laterally movable with respect to each other when the spring component deflects.
