adidas Men's Size 11.5
A adidas men's size 11.5 fits like a standard US 11. Here's that in UK, EU and foot length, and what to order if you measure differently.
adidas runs small, so a men's adidas size 11.5 actually fits like a standard US 11 (UK 10, EU 44, about 27.9 cm). If you measure a US 11, this is your adidas size; otherwise size up half a size from your usual.
adidas 11.5 = US 11
UK 10 · EU 44 · foot ≈ 27.9 cm
What to order: if you normally wear US 11, choose a adidas 11.5. Going by another brand, size up half a size.
| adidas size | Fits like (US) | UK | EU | Foot cm |
|---|---|---|---|---|
| 10.5 | 10 | 9 | 43 | 27.1 |
| 11.5 | 11 | 10 | 44 | 27.9 |
| 12.5 | 12 | 11 | 45.5 | 28.7 |
⚠️ adidas generally runs about half a size small, particularly lifestyle and Ultraboost models; Sambas and Gazelles run long and narrow.
