Insole, from heel to mid-foot, specially developed for sports shoes, but also suitable for casual shoes. The shockabsorbing, anatomically shaped sole consists of a three layer system. The special shock pad strongly reduces impact on the heel and therefore reduces the chance of injury to the heel, Achilles tendon, paw, ankle or feet. The sole also reduces the effect on existing injuries. The ergonomic stabilising cradle provides strong support around the heel and arch to help to keep the foot in the correct position. The flexible material is anatomically shaped and breathable.
