Hike, sled or snowshoe your way through bad weather with these winter boots. Waterproof nubuck leather upper combines Polartec® and Thinsulate® insulation for three-season comfort. The lightweight TPU shell is completely waterproof, close-molded to the foot with easy striding flex ribs at the forefoot. Heel ridges secure a snowshoe strap, and the laces are anchored directly in the shell for precise, athletic lace tension. The tire-chain pattern lugs on the Vibram® sole power up anything.
