Questions shoppers ask
What is UK 4 in US size?
UK 4 is a US men's 4.5 and a US women's 6.5, based on Nike's published footwear charts.

Not always. Brands map their own lasts to size numbers, so the same foot can be half a size different between labels. Measure your foot length in centimetres and compare it with the store's chart when one is available.
