How to find your size
Know your starting size
Use the size printed inside a well-fitting shoe, or measure your foot length in cm.
Read across the chart
Find your size's row — every column in that row is the same size in another system.
When in doubt, size up
Between sizes or between brands, the larger size is usually the safer buy.

Questions
What is a US women's 8 in EU?
A US women's 8 is a UK 6, EU 38–39, and 25 cm (the cm value is also the Japanese and Mexican size). Use the tables below for every size.
How do Japanese shoe sizes work?
Japan sizes shoes by foot length in centimetres — a size 26 means a 26 cm foot, which is about a US men's 8. That's why the CM column converts directly.
What if I'm between sizes?
Size up — especially for sneakers and pointed shoes. Widths also differ between brands, so check the brand's own chart when possible.
