Often imitated, never duplicated—the original Sorel Caribou boot features winter-defying protection and one-of-a-kind look that has been a fan favourite for decades. The shaft is made of high-quality Nubuck leather with a matte, robust appearance and is treated with a water-repellent layer. Due to the seam-locking separation between the leather upper and the foot made of durable rubber, the winter boot is completely waterproof. The 9 mm (removable and washable) ThermoPlus™ felt liner will keep your feet warm all day long. A 2.5 mm felt midsole and thick rubber outsole protect against cold surfaces. The AeroTrac™ outsole provides excellent traction on slippery and rough surfaces. Suitable to wear at temperatures as low as -40°C. A powerful model for rougher work in a cold winter.
