got these for my 6yr old nephew.  he still isn't able to tie his own laces, so the velcro was appealing.  mostly, i think he is going to go crazy over the 'eye' it is very cool.  i ordered a size 4 for him (think he's about 3.5 right now) and it looks true to size. i will post pics after he opens the present this christmas.

12/26-my nephew tried them on and they fit him perfectly. he has loved showing them off the past two days. the eyes light up as he walks (i don't think i was aware of that feature) and the bottom dino print is awesome!

putting up a pic...
