SO again, the issue is the rude people wearing them, not the shoes. Rude people are rude people. Whether they are wearing heely's or
crocs. Or for that matter, parents who don't control/correct their children are going to be unruly in whatever shoes they are wearing (or licking as one post pointed out).
Further, if you are then going to say that saftey is your issue, first, they are no more dangerous, if used properly, than stiletto heels, which I see plently of at WDW & DL. Ever get stepped on by those while wearing teva's??
Second, if your concern is for the safety of the child, it's not your place...it's not your child. The parent needs to be the judge of what their child is capable of or not. Again, parents who don't supervise their children aren't going to no matter what shoes they have on.
And of course my daughter has sneakers. That's not the point and was kind of a ridiculous thing to say. The pointis that they are multi functional and you can't compare them to roller blades, becuase they are not exclusively on wheels, they have a sneaker component as well.
Finally, let's not forget where we are..it's not the opera..it's a kid's (and adults too) playland! Alot of people are just crouchy and need to remember what it's like to be a kid and lighten up.
