The Stabilizing Pro Ankle Brace is designed to meet the needs of demanding athletes. It features 800D ballistic nylon and reinforced eyelet area for outstanding performance and durability. A full circumferential elastic strap secures all strapping and provides tibia/fibula compression and stability. Lace-up design and trimmable figure-8 strapping locks the calcaneus into place and controls inversion/eversion. Removable, articulated medial/lateral stays enhance proprioception and stability. Fits easily into an athletic or street shoe. Universal to fit right and left.A recent study of over 2,000 high school football players proves that wearing the Stabilizing Ankle Brace reduces the incidence of acute ankle injury by 61%. Wearing the brace did not increase the incidence or severity of acute knee injuries or other lower extremity injuries. Bracing also offers a low-cost alternative to athletic tape.
