ABSTRACT:
A walking cane has an enlarged foot piece, formed with a convex arcuate lower surface, that functions as a small rocker. One, or two, rows of spikes extend downwardly from the arcuate surface, for penetration and gripping of icy surfaces. An elastomeric, resilient pad may be attached to the arcuate lower surface of the foot piece, to adapt the cane for use on normal walking surfaces, such as carpets, hard floors, and outdoor sidewalks. The pad has a series of sockets that fit onto the spikes for retention of the pad on the foot piece. The arcuate surface contour on the foot piece is advantageous in that it enables the spikes or resilient pad to maintain a non-slip, rocking engagement with the walking surface during the entire walking stride, i.e., while the person is using the cane to partially support his or her own weight during forward motion of the person's body.
