Fit Guide
Fit can vary by brand and style:
- European brands often run slightly narrower; consider half a size up if you have wide feet.
- US and UK sizes may offer more width options (N, M, W).
- Asian sizing (JP/CN) typically runs smaller—sizing up is common when converting from CM or EU.
When in doubt, check the brand's size chart or order two sizes and return one.
How to Measure Your Foot
Measure your foot length in centimeters for the most accurate conversion:
- Place a piece of paper against a wall on a hard floor.
- Stand with your heel touching the wall and mark the tip of your longest toe.
- Measure from the wall to the mark in centimeters.
- Repeat for both feet and use the larger measurement.
Foot length in CM is the most reliable reference across all regional sizing systems.
