Fit & How to Measure
Our footwear is built with a form-hugging heel cup, sculpted midfoot, and a wider forefoot and toe box — and runs true to size. If you wear thick hiking socks, consider sizing up a half size.
- Stand on a sheet of paper with your heel against a wall, wearing the socks you'll hike in.
- Mark the longest toe, then measure the distance to the wall in cm.
- Match the result to the CM column above to find your US size.
- Measure at the end of the day, when feet are at their largest.

Description
The men's 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.
