These things should be considered the same as any wheeled item such as a bike, skates, skateboard, etc. and banned wherever the aforementioned items are prohibited. And I also believe parents need to take some sort of responsiblity to teach their children about safety and also pay attention to what they are doing. I've had a couple of kids wearing these wheel shoes (or whatever they are called) actually run into my cart and the parents in turn yell at me to be more careful. Now that went over real big with me . . . .
