Nike Men's Size 9

A Nike men's size 9 fits like a standard US 8.5. Here's that in UK, EU and foot length, and what to order if you measure differently.

Nike runs small, so a men's Nike size 9 actually fits like a standard US 8.5 (UK 7.5, EU 41, about 25.9 cm). If you measure a US 8.5, this is your Nike size; otherwise size up half a size from your usual.

Nike 9 = US 8.5

UK 7.5 · EU 41 · foot ≈ 25.9 cm

What to order: if you normally wear US 8.5, choose a Nike 9. Going by another brand, size up half a size.

Nike size	Fits like (US)	UK	EU	Foot cm
8	7.5	6.5	38.5	24.7
9	8.5	7.5	41	25.9
10	9.5	8.5	42.5	26.7

⚠️ Nike tends to run about half a size small — most people size up half, and lifestyle models (Air Force 1, Blazer) run especially snug.
