High perfomance winter boots never looked as good as the Caribou from Sorel. A Sherpa snow cuff and polished stitching gives these boots a look that's every bit as good as its design. Made from waterproof leather with a pigskin lining, these boots are ready to withstand the bitter cold and heavy snow. Even in the extreme cold, vulcanized rubber and Sorel's Aero-Trac non-loading outsole ensure maximum grip, even in heavy snow. The Caribou is easily refreshed, with a washable, removable inner boot made from recycled felt.
