Silicone metatarsal insole made of high strength medical silicone. It offers greater stability to the back of the foot and effectively supports the arch of the foot. It provides an even distribution of pressure thanks to the different silicone density it has. The blue silicone on the metatarsal and heel absorbs the pressure received by the foot from body weight. The perforated surface helps the smooth flow of air and the "breathing" of the foot.
