The fur trappers, loggers and pipeline workers of the frozen Canadian Northland know a thing or two about keeping feet warm – where any misstep can mean permanent damage. That's why they trust their feet to nothing less that the proven warmth and comfort of Sorel. Legendary in places where Northern Lights are routine, they keep your feet oven-mitt warm thanks to 200-gram Thinsulate insulation built into an ingeniously constructed boot. Features a fully waterproof vulcanized rubber foot and a flexible, breathable leather upper that lets water vapor escape so your feet stay dry and therefore warm - because frostbite doesn't deal in forgiveness.
