- The ASO Ankle Stabilizer is one of today's most popular braces for the treatment and protection of ankle sprain injuries. They feature a lace-up stabilizing design for ensuring proper support, and figure-8 stabilizer straps that lock the heel in a neutral position for preventing inversion or eversion injuries. The straps can easily be re-tightened while still inside the athletic shoe and do not stretch out or fray for greater support. The elastic cuff closure provides added compression and keeps the laces together for a clean look ASO Ankle Brace Sizing Chart: For the best fit and support of your new ankle brace, please follow the following sizing information.
