The Mueller ONE Premium Ankle Brace is great for rehabbing inversion ankle sprains and eversion ankle sprains off the court. The secure fit helps support your ankle by slightly restricting awkward and irregular movements to encourage healing. With its improved fit and slender profile, the ONE Premium Ankle Brace feels like having your ankle professionally taped by an athletic trainer. It's a reliable way to help prevent common ankle injuries when you're playing, including ankle strains. To clean, hand wash in cold water with mild detergent. Do not use bleach or fabric softener. Rinse thoroughly and air dry. Antimicrobial treatment helps protect the brace against odor, staining, and deterioration caused by bacteria and microorganisms. The treatment does not extend protection to the skin.
