Provides a 3-fold therapeutic effect: relieves pain, distributes pressure uniformly to reduce impact, and produces a soothing massage effect to prevent fluid buildup. Made with nonbinding, lightweight, breathable knit to remain cool and moves with the foot for maximum comfort without compromising mobility. Anatomically contoured, viscoelastic insert runs alongside the Achilles tendon to provide effective pressure relief, making it ideal for Achilles tendonitis and tendon strains, bursitis of the Achilles, and post-Achilles tendon ruptures. When active, the unique viscoelastic insert with an absorbent, soft terry-cloth lining, provides an intermittent massage to help reduce pain and swelling. Removable silicone heel wedge incorporated in the support raises the heel. Promotes proprioception to increase stabilization. Additional heel wedge provided for the unaffected foot to prevent leg length discrepancy. Provides peak shock-load reduction to joints and back with both heel cushions in place.
