My son loves these and still wears them even though he has gotten some newer ones and these are a little snug now.  They have held up well considering he is VERY rough on shoes.  These have been his school shoes but he now uses them to play in and they're still going strong.  He loves that he doesn't have to tie them, just slip them on.  They actually hold on well haven't worn around the insid of the heel at all.  Too bad they don't offer them in adult sizes which he's now growing into.
