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.
