Embodiments of low cost prosthetic feet (100, 200, 300, 400) include a footplate (120, 220, 320, 420) with a connection mechanism (110, 210, 310, 410) embedded within a first foam element (140, 240, 340, 440) having a first stiffness. A second foam element (150, 250, 350, 450) is bonded to the footplate and has a recess (154, 254, 354) in a proximal surface and a stiffness greater than the first foam element. The second foam element may have a portion (252, 352) extending past the terminal end of the footplate. A cosmesis (130, 230, 330, 430) encloses the components of the prosthetic foot. A third foam element (460) that extends through the cosmesis into the second foam element may be provided. The third foam element may have a higher stiffness than the first and second foam elements. |
