Questions shoppers ask
What is EU 45 in US size?
EU 45 is a US men's 11, 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.
