adidasKids' Goletto VII Firm Ground Soccer Cleats

I have a pair of shoes in my cart but the size says 1-13. What size am I ordering when it says this?

is size 1 little kid bigger than size 13? My kid just outgrew his size 13.5 and needs a size 1, but they're not listed in big kid.

Que size sería si mi niño tiene 5 años

So is the size 1 and 2 actually bigger than the 13? My daughter wears a 2 in big kid
