FairSoleShoe size conversion: UK, EU and US sizes compared
Nesim Yılmaz · 19.10.2026
A UK 8 isn't the same length in every brand. If you buy online, knowing your foot length in centimetres saves a lot of returns.
Measure your feet
- In the evening, wearing socks, stand on a sheet of paper against a wall.
- Mark the tip of your longest toe and measure to the wall.
- Measure both feet and use the larger number.
- Add 0.5–1.5 cm of room depending on the shoe.
