Classic Sorel

Originally developed in 1972, the Sorel Caribou's purpose has always been to keep your feet insulated when shovelling the sidewalks after a frigid mid-winter snowfall. The Caribou features rugged waterproof seam-sealed construction, and heat capturing 9mm ThermoPlus™ recycled felt liner, which is fully removable. Sorel has certified the men's Caribou for use in temperatures as low as -40°C, ensuring the boot will keep your feet warm on commutes to the office, evening walks to the rink, and winter vacations to Banff.
