UltraliteTM is the evolution of winter footwear, where comfort meets agility without compromising style or protection. With highly breathable, waterproof upper materials and a heat-mouldable, removable liner with B-TekTM Lite insulation, this series guarantees weather protection in temperatures ranging from 5°C/41°F to -50°C/-58°F. Weighing only 2lbs per boot, these sit upon a SuperliteTM shell which features a snowshoe ledge. Finally, our proprietary AirGrip® starts in the midsole and is moulded through the outsole, then rounded out with PolarTM Rubber contact points for additional slip resistant grip on snow and ice.
