BACK 70 Size Guide
Consult the BACK 70 charts to compare European (EU) sizes with foot length. The men's chart also includes UK and US size conversions.
How to measure your foot
Place a sheet of paper on a flat surface and stand with your foot on the paper. Mark the heel and the tip of the longest toe, then measure the distance. Measure both feet and use the larger measurement. For the women's chart, use centimeters; for the men's chart, use millimeters.
