Size guide
Measure your foot in the evening, barefoot, heel against a wall: that is when it is at its widest.
How to measure
- Place a sheet of paper against a wall, heel touching the wall.
- Mark the tip of your longest toe and measure the distance in inches or centimeters.
- Compare with the "inches" column below. If your feet differ, go with the larger one.
- Sizes run in half steps. If you are between two sizes, go up for running.
