An insole that extends from the heel to the midfoot, specifically designed for sports shoes but also suitable for casual footwear. The anatomically shaped, shock-absorbing insole consists of a three-layer system. The special cushioning pad significantly reduces the impact on the heel, thereby lowering the risk of injuries to the heel, Achilles tendon, forefoot, ankle, or foot. The insole also lessens the impact on existing injuries. The stabilizing ergonomic cradle provides firm support around the heel and arch, helping to keep the foot in the correct position. The flexible material is anatomically shaped and breathable.
