I don't know if your child is a girl or boy, but alot of girls sneakers have pretty thick soles. I would be careful though b/c I have heard of CM's measuring children w/o shoes on to double check. Those height requirements are to be taken seriously, so if he/she is like an inch shy then maybe the shoes would work(keeping in mind they might check), but anymore than that I would think is dangerous. I know what it's like to not make the height require. I'm only 5ft tall so there were plenty of rides I couldn't go on until way after everyone else, but it's not worth it to chance an accident.
