Stay warm in the Aldarion Insulated Waterproof 8-inch tall men's lace up boot. The 400 grams of 3M Thinsulate Ultra provides maximum warmth and comfort, yet it’s still thin enough to allow complete freedom of movement and is designed for some of the harshest conditions by retaining insulation in damp conditions. The dark chocolate leather exterior features the Chip A Tex waterproof membrane system that's still breathable and has black rubber panels on the toe and heel for added protection.
