Shoe Size Guide

Our shoes follow standard US women's sizing. Measurements are foot length. If you're between two sizes, we recommend choosing the larger one.

Women's Shoes

US Size EU Size Foot Length (in) Foot Length (cm)
5 35 8.5 21.6
6 36 8.9 22.5
6.5 37 9.1 23.0
7.5 38 9.4 23.8
8.5 39 9.7 24.6
9 40 9.9 25.1
10 41 10.2 25.9
11 42 10.5 26.7
12 43 10.8 27.4

Conversions are approximate. When a product lists both a US and an EU size, the EU size is the manufacturer's reference size.

How to Measure Your Foot

  1. Stand on a sheet of paper with your heel against a wall.
  2. Mark the tip of your longest toe.
  3. Measure from the wall to the mark.
  4. Measure both feet and use the longer measurement.

Measure at the end of the day, when your feet are at their largest.

Fit Notes

  • Ankle boots: If you plan to wear thick socks, size up.
  • Slippers: Sized for a relaxed fit. Take your usual size.
