What size Birkenstock should I get, and how does EU convert to US?
Birkenstocks are sized in EU sizes only. A women’s US 8 is EU 39 and a women’s US 10 is EU 41; a men’s US 8 is EU 41. Because there are no half sizes, measure your foot length and match it — if you’re between sizes, size down. Pick Regular width for medium-to-wide feet or Narrow for narrow-to-medium.

Birkenstock Sizing & Fit Guide
Birkenstock is sized in EU sizes with no half sizes, so measure your foot length and match it — US conversions span a half-size range. Sandals come in two widths: Regular (medium to wide) and Narrow (narrow to medium); the footprint icon on the box is outlined for Regular, filled for Narrow. If you’re between sizes, size down — the cork footbed moulds to your foot with wear.
