Boot fit guide

Cairn boots and shoes fit true to size for most people, with a medium width and a roomy toe box for downhill miles.

Measure at the end of the day

1. Stand on a sheet of paper wearing the socks you hike in.
2. Mark the heel and your longest toe and measure in centimeters.
3. Add 1 cm for thumb room and match it to the size chart on the product page.

Wide feet

We don't make wide sizes yet. Many wide-footed hikers go up half a size and use a thinner insole, or choose the Cairn Low, which has a softer upper.
