The Glaciator is designed to keep tennis players feet cool and dry in the heat of a match. • The Fautex moisture-management technology in the lining allows feet to stay drier and cooler, while the Heat Deflection Core deflects surface heat away from the foot. • The DuraWrap™ XDE high-abrasion toe guard provides durability and breathability. • These features work simultaneously to provide unsurpassed cooling and ventilation. • This version of the glaciator is all over mash, for extra ventilation.
