Nike Men's Size 8

A Nike men's size 8 fits like a standard US 7.5. 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 8 actually fits like a standard US 7.5 (UK 6.5, EU 38.5, about 24.7 cm). If you measure a US 7.5, this is your Nike size; otherwise size up half a size from your usual.
Nike 8 = US 7.5
UK 6.5 · EU 38.5 · foot ≈ 24.7 cm

What to order: if you normally wear US 7.5, choose a Nike 8. Going by another brand, size up half a size.

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