How to measure

Refer to your usual shoe size first, then confirm it: place a sheet of paper against a wall on a hard floor, stand with your heel to the wall and trace each foot. Measure heel to longest toe in centimetres and read the chart from your larger foot.

Check the fit

Your toes should lie flat and only just brush the front of the liner — never crushed. The heel should sit locked with no lift when you flex your knees forward. K2 boots pack out a little as the liner beds in.
