How do I measure my foot length?

Stand on paper against a wall, mark the tip of your longest toe, then measure from the wall to the mark in millimeters.

Which foot should I use?

Always use the longer foot. Most people have a difference of 2-5mm between feet.

Foot length → shoe size

Enter your longer foot’s length for an adult reference based on Nike’s men’s-based chart. Results show the next published foot-length anchor, not a universal brand conversion.

How to measure your foot

Place a sheet of paper flat against a wall on a hard floor.
Stand on it, heel touching the wall, wearing the sock you'll use.
Mark the tip of your longest toe.
Measure from the wall edge to the mark in millimeters.
Repeat for the other foot. Use the larger value.
