These insoles have three areas of protection creating a more pleasant walk, the front sole, the heel sole and support for the foot. They are made from Aeroshoes® material, a thin material that avoids the damp feeling caused by perspiration in the shoes. The Epithelium 26® silicone gel module, positioned in the plantar zone, distributes the load to prevent and relieve plantar pain and calluses. The heel is made from a shock absorbing material, which reduces the strain placed on the spinal column when walking. Available in sizes 3 to 12 (no half sizes).
