With the Sorel Caribou WP boots, you can get through even serious sub-zero temperatures without getting cold feet. The boots keep moisture out with waterproof nubuck leather and vulcanized rubber and keep you warm with the removable thermal inner boot and a midsole made of warm felt. The boots have an all-round waterproof design, including sealed seams, and a winter-ready treaded sole. Winter can come with these boots.
