Waterproof and warm, the Sorel Timberwolf Leather Winter Boots will get you through the cold winter season. The waterproof, polyurethane-backed leather uppers are seam sealed for protection against the elements while the 400g Thinsulate® polyester fiber insulation offers added warmth and a comfort rating of -40°F. Polyester linings help wick away moisture from feet while the removable EVA footbeds and EVA midsoles cushion every step and offer additional thermal protection. Molded thermoplastic urethane toe bumpers protect uppers and feet, while molded heel ledges help keep snowshoe heel straps in place. The rubber outsoles with multidirectional lugs deliver dependable traction on wet or dry surfaces.
