The original Sorel Caribou is still a favourite for all-purpose winter work and play. Seam sealed leather upper and a vulcanized rubber shell are burly enough to withstand Canadian winters, and the 9mm wool felt liner provides reliable warmth. Like a wooden toboggan and a plaid hat with earflaps, these are a winter classic for a reason, Sorel has wisely kept the original design largely unchanged. Seam sealed waterproof nubuck leather upper for full waterproof protection. Removable ThermaPlus felt inner boot with a wicking inner layer for moisture management and a reflective thermal membrane for warmth. Sherpa Pile snow cuff keeps snow out. Vulcanized rubber lower shell for durability. Midsoles with a 2.5mm bonded felt frost plug insulate against ice and snow. AeroTrac rubber outsole gives traction on snow surfaces.
