The Sawtooth Ascent Insulated Waterproof winter boot looks at a cold, wet forecast and doesn't blink. Insulation handles the chill, B-DRY waterproofing seals out the wet and a Vibram outsole holds firm when trails go icy and unpredictable. The kind of winter shoe that makes cold-weather hikes feel less like something you endured, and more like something you chose on purpose.
