Low-profile design constructed with non-stretch nylon for comfort, performance, and durability. Fits easily into athletic or street shoe. Universal to fit right or left. Lace-up design and figure-eight strapping locks the calcaneus into place and controls inversion/eversion. A wrap-around elastic strap secures all strapping to provide superior tibia/fibula compression and stability. Removable medial/lateral stays provide enhanced proprioception and stability.
