Are you preparing for an expedition in the Arctic Circle, Greenland, or the Canadian Far North? The Sorel Glacier XT men's winter boots are made for you. Designed for use in the coldest conditions on Earth, the Glacier XT will prevent you from losing toes or your foot during the expedition. The insulation of these Sorel boots, rated down to -73°C, is achieved with a 13 mm ThermoPlus insulating liner, as well as an Omni-Heat™ reflective lining. The combination of the two allows for exceptional and unmatched heat retention on the market. Undoubtedly one of the warmest shoes in the world, the Sorel Glacier XT will accompany you on all your polar adventures. The exterior coating of polyurethane-coated fabric makes your Sorel boots windproof and water-repellent. Additionally, for optimal closure of the Glacier XT boots, you will find a barrel lock closure at the top of the boots. In such conditions, a fall could prove fatal. For this reason, the Sorel Glacier XT boots are equipped with a Sorel™ AeroTrac™ outsole, incredibly grippy on all terrains. Indeed, this outsole does not retain snow or dirt and is completely waterproof. Add to this a 13 mm antifreeze midsole that withstands the most intense cold. Whether you're heading out to meet polar bears or on an Antarctic expedition, these boots will be indispensable for withstanding the coldest temperatures on the globe.
