Abstract: A prosthetic device and related methods having height adjustment features. A prosthetic foot includes an elongate support member comprising fiber reinforced material and having a support surface configured to rest upon a ground surface prior to use, an adapter mounted to the support member and configured to secure the prosthetic foot to another prosthetic device, and a height adjustable feature configured to adjust a height of the adapter relative to the support surface.

Abstract: A prosthetic device includes a footshell having a first portion and a second portion. The first portion has a first portion polymer lattice structure and the second portion has a second portion polymer lattice structure. The first portion polymer lattice structure has a first set of mechanical properties and the second portion polymer lattice structure has a second set of mechanical properties different from the first set of mechanical properties. The footshell also includes a sole attached to a bottom of the first portion and the second portion, wherein the sole is formed of a solid material.

Abstract: A prosthetic device includes a polymer lattice structure. The lattice structure includes a first surface arranged to face toward a residual limb, a second surface arranged to face away from the residual limb, a thickness between the first and second surfaces, and a variable lattice density across the thickness.
