All sizes are EU whole sizes — no half sizes. *US conversions are approximate: a whole EU size often falls between two US sizes. If your US size or foot length lands between two rows, choose the larger EU size.

How to measure your foot

Place a sheet of paper on the floor against a wall. Stand on it barefoot, heel touching the wall.
Mark the tip of your longest toe on the paper with a pencil.
Measure the distance from the edge of the paper (wall side) to your mark.
Compare your measurement with the Foot length column above and read your size across.

Tip: measure at the end of the day — feet swell slightly — and use your larger foot.
