My son loves spiderman, so i got these in 9.5 and 10 and neither of them fit him and he just turned 3, so i went to zappos and ordered the style with with the red lights (his choice) in a 10 wide and he says they fit perfectly, but i think he will be able to wear these for a couple years, hopefully, but this style without the lights is too hard to put on, there is no elastic to stretch to get your foot into the shoe.
