Inline skating
（重定向自Blading）
Inline skating is a sport practiced widely internationally. Inline skates typically have 2 to 5 polyurethane wheels, arranged in a single line, although 5 wheel designs are no longer manufactured. The in-line design allows for greater speed than roller skates and better maneuverability. The in-line wheels are coupled with boots designed for skating over and around various obstacles. Inline-skating is practiced and performed using inline skates designed for race tracks, skate parks, Urban areas, and off-road.
