Enter your EU size to see the US equivalent.
The EU to US shoe size converter translates any European EU shoe size into its US equivalent for men and women. This tool is essential when shopping from European brands like Birkenstock, Adidas, or buying shoes abroad. The most important thing to know: EU 40 does not equal US 10 — EU 40 equals US men's 7. Always select the correct gender for an accurate result.
⚠ Common mistake: EU 40 ≠ US 10. EU 40 = US men's 7 or US women's 9.5. US men's 10 = EU 43.

Frequently Asked Questions
What is EU 42 in US size?
EU 42 = US men's 9 (UK 8.5, 26.0 cm) or US women's 11.5 (UK 9.5). The same EU number maps to a different US number depending on gender.
What is EU 38 in US?
EU 38 = US men's 5.5 (UK 5) or US women's 7.5 (UK 5.5).
Is EU 40 the same as US size 9?
No — this is the most common shoe size mistake. EU 40 = US men's 7, not US 9. US men's 9 = EU 42.
Why do EU and US sizes not match up neatly?
EU sizing uses Paris points (⅔ cm increments) while US sizing uses barleycorn units (⅓ inch increments). Because the increments are different sizes, not every EU size has a perfect US half-size match.
Do EU sizes vary between brands?
The number is standardized, but the actual fit varies because each brand uses its own shoe last shape. An Adidas EU 42 and a Nike EU 42 represent the same foot length but may feel different in width or volume.
