The SuperiorArch^® has a custom designed incline molded into the select wood base. This allows room for the heel to rotate down avoiding impingement of the heel bones. High Density Foam Pads are placed at the arch and heel contact points. The SuperiorArch^®is completely covered with two inch Premium Foam for foot comfort. An adjustable Velcro Flap properly secures any size foot to the SuperiorArch^®.
