CrocsToddlers Crocband Clog T

I see that a toddler size 6 is an option... Is this really a 6 or do they mean 6/7? I've never seen crocs use just one size.

Is 10-11 little kid same as toddler?

My daughter is j4(35-36 european size) what size should i buy only gives me the option of toddler-4 i do not understand?

Si hija tiene 15.5 cuál debería pedir ? Ella tiene 3 años 6 meses
