Questions shoppers ask
What is US men's 4 in EU size?
US men's 4 is EU 36 and UK 3.5, based on Nike's published footwear charts.
Will this size fit every brand?
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.
