How to measure your foot
- Stand on a sheet of paper, heel against a wall, wearing the socks you'd wear with the shoe.
- Mark the tip of your longest toe and measure from the wall to the mark (do both feet; use the longer one).
- Find that length below. Between two sizes? Go up half a size — most of our styles run true to size, and any size note on the product page overrides the chart.

EU brands (Back 70, Manebi, Birkenstock…) use whole and half EU sizes, and each designer converts a little differently. Still unsure? Call 833-608-5199 or visit any of our 10 boutiques — we'll fit you in person.
