Please be aware that due to an internal error at Veja a mistake has been made in the translation of European to UK sizes. Be aware that European sizes do remain the same and is consistent. For example, for AW22 sizes a European size 42 is labelled as a UK7.5 however the sizing is equivalent to a UK8. This will be corrected for Spring 2023.
