A removable sanitary cover for a leg extremity of a cane, walker, crutch, and the like, to reduce dirt and contaminants coming into from outdoors or dirty environment into an indoor or sanitary area. The sanitary cover includes a base and at least one sidewall that together form an enclosure having an opening generally opposite of the base. The sanitary cover also includes a closure positioned generally circumferentially about the enclosure at the at least one sidewall near the opening. In use, the sanitary cover is positioned about a distal end of the leg extremity of the cane, walker, crutch, and the like, with the closure keeping the sanitary cover in place relative to leg extremity until the sanitary cover is removed through an external force. The closure may be an elastic band, drawstring or other closure means. An optional skid-resistant material may be added or otherwise incorporated into an outer surface of the base.
