ABSTRACT:
A cane having a base formed from a cup-shaped support having a concave bottom surface and a top surface defined by a circumscribing exterior sidewall having a bottom edge. The concave bottom surface is formed to have a plurality of resilient projections extending therefrom a distance to project slightly beyond the bottom edge of the sidewall. The projections are formed in a spoke-like pattern on the bottom surface such that the density of the projections is greater near the central section of the bottom surface than at the periphery of the bottom surface. The projections are also formed to have a length that varies according to their position on the bottom surface so that a substantially planar contacting edge is presented to a support surface.
