How to Measure Your Foot
- Place a sheet of paper against a wall and stand on it with your heel touching the wall.
- Mark the longest toe on the paper, then measure the distance to the wall in cm.
- Add 0.5 cm for sock allowance and match the result to the CM column above.
- Measure at the end of the day, when feet are at their largest.
