The Sorel Men's Caribo™ Winter Boots are often imitated but never equaled. The original Sorel boot features a nubuck leather upper with waterproof construction and seam-sealing to keep your feet dry. A removable ThermoPlus felt inner boot adds warmth, comfort and protection in cold and wet winter weather. The outsole gives you great traction so you can navigate slippery or rocky terrain. The Sorel Men's Caribou™ Ski Boots features winter-defying protection and one-of-a-kind look that has been a fan favorite for decades.
