How to measure

- Stand on paper with your heel against a wall.
- Mark the tip of the longest toe and measure from the wall.
- Measure both feet and use the longer measurement.
Between sizes?
Choose the smaller size for a closer fit or the larger size for a more relaxed fit. For wide feet, consider the larger option where available.
