The Sorel Avalanche Trail Boot is a warm and durable cold-weather boot for men. This boot is waterproof, so you can easily wear it in snow and sleet. It's also extremely insulated, so it will keep your feet warm. The durable rubber lower section makes the Avalanche Boot great for work, rugged adventures, or heavy everyday wear. The upper is a sleek full-grain leather, lined with microfiber to feel soft and comfortable against the skin. Since you'll likely be on your feet a lot in this boot, Sorel added a padded footbed for comfort.
