UK, EU, US: Shoe Sizing Finally Explained
Why your UK 4 is suddenly an EU 36.5, and how to actually find your size.
Shoe sizing is a mess. Three different systems, half-sizes that exist in some and not others, and brands that interpret each system slightly differently. Here's the honest version.
UK and US sizing differ by 2. A UK 4 is a US 6 in women's. Always. This is the easiest conversion.
EU sizing is based on millimetres. Specifically, the length of the last (the wooden form a shoe is built around) in 'Paris points' — each point is 6.67mm. Whole numbers don't always map cleanly to UK sizes, which is why you see EU 36.5 even when UK doesn't have a half size.
Brand variation matters more than system. A UK 4 in one brand might fit like a UK 4.5 in another. This is why measuring your foot in centimetres and matching to a brand's specific chart is more reliable than picking a number.
Our recommendation: measure your foot at the end of the day (when feet are largest), match to our size chart, and if you're between sizes, go up. Free returns within 30 days mean there's no risk in trying.
