How to Measure
- Place a piece of paper flat on the floor against a wall.
- Stand on the paper with your heel touching the wall, wearing the socks you usually wear with shoes.
- Mark the longest point of your foot (usually the big toe) on the paper.
- Measure from the wall to the mark in centimetres.
- Match the length to your UK size in the chart above.
Fit Tips
- Measure both feet — most people have one foot slightly larger. Always size to the larger foot.
- Measure at the end of the day when feet are at their largest.
- Platform sneakers run true to size; loafers run slightly narrow.
- If between sizes, we recommend sizing up — our insoles can be adjusted with a half-size insert.
- Free returns within 30 days if the fit isn't right.
