This walker is redesigned with slotted stirrups that maintain ideal strap separation to conform to the leg and immobilize the ankle. It has an ultra low profile design that eliminates height difference between walker and normal shoe without altering gait. The padded liner is vented promoting air circulation which keeps the lower leg cool and comfortable. Anatomically contoured spatula stirrups immobilize the ankle comfortably while the shock absorbing insole has pressure moldable characteristics which conform to the foot. Color : Black.
