As mentioned in other reviews, I thought I was purchasing youth/big kid size (as oulined in the drop down menu to choose sizes) but the seller sent toddler/kid youth large equating to size 1-2. These also seem to run small so be sure to buy a size bigger, especially if you wear sock with your slippers. Haven't had them long enough to say if the bottom wears out fast as others have mentioned but they do look sharp.
