Size Guide – Peak 8

Peak 8 shoes are built on one true-to-size last across the whole range. If you’re between sizes, we recommend sizing up half a size for more room, especially for trail and alpine styles worn with thicker socks.

How to Measure at Home

Stand on a sheet of paper with your heel against a wall.
Mark the tip of your longest toe, then measure the distance from the wall to the mark in centimetres.
Measure both feet in the evening, when feet are at their largest, and size to the bigger measurement.
Compare your measurement against the length chart on each product page.

Fit by Category

Road & street: true to size, standard volume.
