ABSTRACT:
A crutch tip assembly (12) includes a crutch tip base (14) with a laterally protruding lip (28) adjacent a base bottom surface (26) and a resilient boot (16) having the shape of a rocker. The boot defines a mounting cavity (36) for snugly receiving the base bottom surface and the lip for holding the boot on the base. The boot has a sole with a bottom surface (39) for contacting the ground and a top surface (46) in the cavity directed towards the base bottom surface. Protruding portions are positioned between the base bottom surface and the sole top surface for providing resilient cushioning between the sole top surface and the base bottom surface. Sidewall cavities (84) are located around the perimeter of the boot allowing for lateral compression and reexpansion.
