I love Crocs for kids (not so much for adults, personally).  My 4 y/o has always worn them and loved them and then I recently bought these for my 16 month old.  He is definitely wearing a size 5 shoe for all his other shoes but these just fall off of his feet.  I wish I had bought them a size smaller - these run just too big.  But hopefully he'll grow into them. They seem like good shoes.
