UGG Men's Size 11.5
A UGG men's size 11.5 fits like a standard US 12. Here's that in UK, EU and foot length, and what to order if you measure differently.
UGG runs large, so a men's UGG size 11.5 actually fits like a standard US 12 (UK 11, EU 45.5, about 28.7 cm). If you measure a US 12, this is your UGG size; otherwise size down half a size from your usual.
UGG 11.5 = US 12
UK 11 · EU 45.5 · foot ≈ 28.7 cm
What to order: if you normally wear US 12, choose a UGG 11.5. Going by another brand, size down half a size.
| UGG size | Fits like (US) | UK | EU | Foot cm |
|---|---|---|---|---|
| 10.5 | 11 | 10 | 44 | 27.9 |
| 11.5 | 12 | 11 | 45.5 | 28.7 |
| 12.5 | 13 | 12 | 47 | 29.5 |
⚠️ UGG runs about half a size large and moulds to the foot — size down half, or a full size for slippers.
