What’s the coolest kind of transportation(交通) for middle school students back from winter holidays？ A racing bike？ A car？ No, it’s a special kind of shoes called Heelys(暴走鞋). Heelys look just like common sports shoes, but they have a wheel(轮子) hidden(藏) in the heel(鞋跟). So instead of walking, kids can “fly” around in them. “Wearing Heelys is fun and cool!” said Wu Peng, a boy who wore them on his first day back at No. 6 Middle School in Beijing. Wu Peng said he loves the shoes so much that he wears them to go here and there. Sometimes he even follows his parents’ car to the supermarket in his Heelys!
