The Glacier XT winter boot from Sorel impresses with its excellent isolation even in extremely cold temperatures. The robust upper material is waterproof and windproof, while Sorel's typical raised rubber sole provides additional protection. The removable ThermoPlus inner boot made of felt has a new Omni-Heat® Reflective lining. This helps to regulate body temperature by reflecting and returning body heat. An ideal winter shoe for marveling at the dazzling northern lights, catching the first fish from the ice hole or simply enjoying the icy cold winter days with warm feet at all times.
