Abstract:
1. A prosthetic foot comprising: a first foam element having a first stiffness; a second foam element having a second stiffness different than the first stiffness of the first foam element; a resilient footplate embedded within the first and second foam elements, and having proximal and distal surfaces, and anterior and posterior portions; wherein the first foam element is disposed along the proximal surface of the footplate and the second foam element is disposed along substantially the entire distal surface of the footplate; a third foam element having a third stiffness that is greater than the first and second stiffnesses of the first and second foam elements, respectively, the third foam element extending into the second foam element spaced from the distal surface of the footplate; and an outer shell defining a cosmesis surrounding the first and second foam elements wherein the third foam element extends through a distal posterior surface of the cosmesis into a distal posterior portion of the second foam element.
