The closed-cell foam will not absorb water or sweat, and like all Airex products the foam contains an anti-microbial treatment to increase the durability of the products. Airex Balance Pads are the choice of professionals to help restore balance and improve stability and coordination. The pads are excellent for retraining lower extremity function, and for improving coordination and stamina. All Airex products are manufactured in Switzerland.
