They are too big
I bought this shoes to my kid, he is in between size 13 and 1Y, I chose 1Y for him, and they are too big. On line there is the option of sizes 1Y, 2Y and 3Y and they came as size 1-3 Y. To buy this your kid should be definetly in the youth sizes. If I had known this, I would have chosen a 13. They are big in lenght and wide.
Anyway, they look as nice and confortable as any other crocs.
