How do Nike shoes fit?

Nike shoes run small — size up about half. Here's what to know before you buy.

Nike footwear tends to run small and narrow, especially running and training models. Most people size up half a size. The Air Force 1 is roomier. Nike uses a full-size US-to-UK offset (US 10 = UK 9).

Fit varies by model and foot. Measure your foot length in cm and match it to Nike's size chart, then adjust using the fit note above.

Quick tip

Switching to Nike from another brand? Don't assume the same number fits — check your foot length against their chart. See how to measure your foot.
