DESC: Anatomically contoured silicone inserts leave the malleoli pressure-free and provide intermittent compression to the soft tissue of the joint, leading to increased circulation and reduced swelling. Ideal for chronic swelling and soreness due to past injuries, grade II sprains, post-cast, post-ankle fixation, degenerative joint disease, synovitis, and vascular ulcers. Machine washable. Caution: This product contains natural rubber latex which may cause allergic reactions.
