The conversion between US and UK sizes and the matching EU sizes is done differently for Nike shoes from the ISO conversions calculated by the Shoe Size Calculator. Nike sports shoes, for example, are often much smaller than the specified EU shoe sizes would suggest. Hence, Nike disregards the ISO specification and its theoretically calculated size measurements and carries out its own conversions between the EU, UK and US shoe-size systems. The Nike shoe-size charts, as published internationally by Amazon, among others, are presented below for women, men and children.
