Armond Williams, Markell McCoy and Kevin Horne are all relatively new to the world of Heelys, a popular shoe with a wheel installed in the heel.

The wheel creates a mix between roller skates and tennis shoes, allowing kids, and even adults, to go between walking and skating with ease.

"When you skate people always say, 'ooh, where did you get them shoes from?' A lot of people say that."

The three youngsters are at Highland Park with the Boys and Girls Club of East Mississippi. Director Ricky Hood said he gets nervous when the kids wear Heelys and has asked them not to, but has not officially banned them from his organization.

"For me, they're dangerous because they're on their heels and they call them Heelys. If they fall backwards, they're going to hit their head and I'm really concerned," said Hood. "Any time you fall and hit your head, it's dangerous."

Due to the increase in roller shoe related injuries, some safety groups are asking parents to make sure that their kids are wearing helmets and wrist protection when wearing the shoes. That's something that Hood says is necessary, but may not be possible.

"The problem with putting the helmet on is that these kids are just walking down the mall and they decide to get on the heels of them," said Hood. "So it's going to be hard to monitor and control."

Williams, McCoy and Horne say they choose not to wear helmets, not because they're not cool, but simply because they don't feel like wearing them.
