Abstract
The invention is for a foot assembly for a walking aid. The foot assembly is attached to a strut at a lower end of the walking aid. The foot assembly has a cylinder attached to a bottom of the strut and a foot pivotally attached to the cylinder by a foot bolt. The foot has a hemispherical portion and a flat ring portion. The foot bolt is positioned through a dome hole and a cylinder bottom opening, and the foot bolt is secured by a foot bolt nut that tightens on the foot bolt threads to attach the foot dome hemispherical portion to a concave cylinder bottom wall. A resilient foot pad is attached to a bottom of the foot. A spacer fits on the foot bolt and retains the foot bolt head inside the hemispherical portion.
