Experience immediate relief from Achilles' tendonitis and return to your normal activity level without missing a step. Even if you don't stretch enough before you exercise or inflexibility is starting to creep up on you, don't let that slow you down. The Pro-Tec Achilles' Tendon Support applies focused compression on the Achilles' tendon while providing lift to the heel, reducing stress where the Achilles' tendon attaches to the heel. Cool Max covered felt with Velcro straps can be easily adjusted to provide just the right amount of support. Machine wash, air dry. One size fits all.
