This large based ferrule will fit walking aids with a 19mm (3/4") diameter shaft and offers improved safety and stability for the user. This is achieved through its large, six finger base which is made from a durable, heavy duty rubber compound which offers excellent traction on many surfaces, allowing the user to walk with confidence. The cane tip flexes as you walk, absorbing the shock of each step to effectively reduce fatigue in the hand and wrist. This replacement rubber foot also enables many types of canes and walking sticks to stand upright by themselves which keeps your walking stick to hand and reduces the need to balance the walking stick against an object when out and about or in the home.
