heelys

The authors weren´t sure why more girls were injured and speculated that perhaps more girls wear Heelys.

作者不能确定为什么女孩受伤的比较多，可能大部分的暴走族是女孩吧。

The Heelys company says the product is safer than biking, skateboarding, basketball, soccer and even tennis. But the other sports have more children participating. And is Heeling even a sport?

暴走鞋公司说他们的产品比脚踏车、滑板、篮球运动足球甚至比网球运动都安全，但是其他的运动有很多孩子参与，何况暴走算是一种运动吗？
