Measure both feet while standing, then use the longer foot. Conversions are approximate: sizing can vary by brand and shoe style, so follow the size chart on the product when one is provided.

Measure your foot

1. Place a sheet of paper against a wall and stand on it with your heel lightly touching the wall.
2. Mark the tip of your longest toe and measure from the wall to the mark in centimetres.
3. Compare that length with the chart. If you are between sizes or prefer extra toe room, choose the next size up.

The centimetre measurement is the length of your foot, not the inside length of the shoe. US and UK conversions are general references and may differ between brands.
