Our football boots use the US sizing system. The following table will help you convert European (EUR) and UK / Australian (UK) sizes to the correct US size. For example, the chart shows that a UK / Australian size 9 is the equivalent of a EUR 43 and a US size 10. The table also helps you work out your shoe size based on the length of your foot. For example, if your foot is 270mm long, you will require a shoe that is 285mm long: EUR 42 / UK 8 / US 9.
