Adidas runs about half a size larger than most US brands, so a US 10 in Adidas typically converts to a UK 9.5 rather than the UK 9 you might expect elsewhere. Use the tables below to convert between US, UK, EU and CM (foot length) sizing before you order. If you’re between two sizes, or want the full fit breakdown by model, see our Adidas sizing guide.
Men’s Adidas Size Chart

Women’s Adidas Size Chart
Adidas women’s sizes run on the same last as men’s, offset by one US size — a men’s US 10 and a women’s US 11 share the same EU size and foot length.
| US | UK | EU | CM |
|---|---|---|---|
| 5 | 3.5 | 36 | 22 |
| 5.5 | 4 | 36.7 | 22.5 |
| 6 | 4.5 | 37.3 | 23 |
| 6.5 | 5 | 38 | 23.5 |
| 7 | 5.5 | 38.7 | 24 |
| 7.5 | 6 | 39.3 | 24.5 |
| 8 | 6.5 | 40 | 25 |
| 8.5 | 7 | 40.7 | 25.5 |
| 9 | 7.5 | 41.3 | 26 |

How to Use This Chart
Measure your foot length in centimeters from heel to the tip of your longest toe, in the afternoon when feet are slightly swollen, and match it to the CM column — this is more accurate than converting from a size you wear in another brand. Remember that Adidas uses a half-size offset between US and UK (a US 10 is a UK 9.5, not a UK 9), which trips up shoppers used to Nike’s full-size offset. If you’re between two sizes, most wearers should size down for a snugger, more responsive fit and size up for extra room.
Frequently Asked Questions
Does Adidas run true to size?
Adidas generally runs true to size to slightly large. Many styles, especially in the Originals line like the Samba and Gazelle, fit true or a touch roomy, so some wearers prefer sizing down half a size for a snugger look.
Is Adidas sizing the same as Nike?
Not quite. Adidas converts US to UK with a half-size offset (US 10 = UK 9.5), while Nike typically uses a full-size offset (US 10 = UK 9). Always check the CM foot-length column when comparing sizes between the two brands.
What EU size is a US men’s 10 in Adidas?
A US men’s 10 converts to EU 44, UK 9.5, and 28 cm foot length in Adidas sizing.
