Combining a classic lace-up design with features giving you better comfort and protection during sports and daily use, our Hi-Flexibility Support helps protect the ankle from rolling or twisting, while still allowing for flexion and extension. Medial and lateral cutouts accommodate convex shape of the malleoli for a better fit. Inset strap helps protect the anterior talofibular ligament from injury in an inversion sprain. Internal spiral stays provide flexible support without the bulk. Available in S, M, L or XL; specify right or left.
