The Stability insole gives optimal support to the heel and midfoot. It absorbs excess perspiration and promotes an optimal fit. Also by providing lateral support to 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.
