An improved crutch tip construction. The crutch tip is formed of a resilient material and has an upper tubular stem portion formed with an axial recess and a lower enlarged head. A concave metallic socket with a reversed upper lip portion is disposed at the bottom of the recess and the lower end of the crutch bow is engaged with the socket. The lower surface of the head of the tip is generally convex and is formed with a plurality of concentric grooves. The combination of the metal socket with the convex lower surface of the head provides a greater surface area of contact between the tip and the supporting surface during use, thereby achieving greater safety for use of the crutch.
