The OS1st AF7 Ankle Bracing Sleeve is perfect for proving ankle stabilization without completely immobilizing the ankle. This sleeve uses a special woven design – K-Zone Bracing Technology – to provide both medial and lateral stabilization and to prevent excessive or unsafe motion of the foot and ankle. The sleeve features 7 zones of medical-grade compression technology that supports the arch of the foot, stabilizes the ankle and achilles tendon, and provides overall foot stability and support. The entire brace is made as a slide-on foot sleeve that can be worn under most socks.
