Abstract
A foot plate for a prosthetic foot includes a sole plate and a layer with laterally variable stiffness disposed above the sole plate. The layer has a medial portion and a lateral portion. The lateral portion has a stiffness different than a stiffness of the medial portion, such as a greater stiffness to provide a relatively softer instep and a relatively stiffer out-step.
