Kids Alexander McQueen oversized lace up sneakers worn

These are a pair of worn kids Alexander McQueen lace up sneakers in a size 31. Which I believe is equivalent to a US 13. I’m not 100% certain so please confirm online with a size chart. This sneaker does have blue dye from jeans on the laces not to noticeable. They are authentic. All pics are of actual item except the cover photo which is a stock photo
