The Achilles Heel Protection Sleeve is ideal for relief from pump bumps, like Haglund deformity. The heel sleeve is also great for sore, fatigued or injured Achilles tendons. THe Achilles Heel sleeve is soft with a comfortable gel pad the fully protects the posterior of the heel, the Achilles tendon area, from friction. The heel sleeve also gently compresses the heel area and reduces pressure. Because the heel sleeve is slim, it fits in most regular footwear. Washable and reusable.
