A nonslip foot assembly for the lower end of a crutch, cane, walker or other walking aid. An expansible sleeve is anchored in the end of the crutch by rotating a threaded bolt in order to squeeze the sleeve between a pair of nuts. The end of the bolt projects out of the crutch and is pivotally pinned to a nonslip foot formed by a rigid disk bonded to a resilient pad having a plurality of projecting fingers. The fingers flex when applied to a hard surface and their resiliency applies a firm gripping force even if the surface is slippery. The fingers are able to dig into carpets and other soft surfaces to provide a firm grip without damaging the surface.
