The Stability Plus insole provides optimal heel and midfoot support. Equipped with metatarsal support (for sagging forefoot). Absorbs excess perspiration and promotes optimum fit. Also due to the lateral support of the foot. The antimicrobial top layer made of X-Static with silver fibre is moisture- and heat-regulating. Unpleasant odours do not stand a chance. X-Static is thermodynamic. Excess heat is dissipated, preventing blistering.
