Adjustable crutches for everyday mobility and physical recovery periods. The closed fixed armband enables the user to retain the crutch on their arm even if they release their grip on the handle. This prevents the crutch from dropping to the floor accidentally. Non-marking ferrules are slip-resistant, for added safety. The 22mm ferrules are fitted to the adult crutches, and 16mm ferrules are fitted to the children’s crutches. Adjustment is easy using the simple push-pin operation. The standard plastic hand grip is easily wiped clean to reduce the risk of cross-infection.
