[ 02 ] · the method

How to measure.

/ 01

Stand

Place a sheet of A4 paper on a hard floor against a wall. Stand on it with your heel touching the wall, full weight on the foot.

/ 02

Mark

Mark the paper at the tip of your longest toe (not necessarily the big toe — check yours).

/ 03

Measure

Use a ruler to measure heel to mark, in centimetres. Add 5 – 8 mm of toe room.

/ 04

Match

Use the chart above. Always measure both feet — pick the larger one.

[ 03 ] · the close call

Between sizes?

// HEX-SLIDE

Runs true to size.

Closed-cell lattice has zero stretch. If you're between sizes, size up for comfort.

// AERO-SLIP

Runs slightly relaxed.

Open-knit upper has give. If you're between sizes, size down for a snugger fit.
