The Addict footbed is completely flat and supports the natural function of the foot muscles and their strengthening. Due to the protective properties of the 6mm EVA foam, it is ideal for sports, especially running and jogging. There is an additional 3mm thin EVA heel cushion under the heel, e.g. for long periods on hard surfaces (asphalt). The footbed is covered with textile (hand wash). After approx. 500km of wear, it can happen that the footbed wears down and should be replaced with a new one in order to avoid pain or injury.
