Unlike traditional roller skates, inline skates have four or five wheels arranged in one straight line and a heel stop for braking. A French inventor patented the first inline skate in 1819.
A pair of black inline skates, with red and gray accents, is photographed on a white background. The skates are positioned to allow the viewer to see the profile of one, and the top of the other. The skates have four polyurethane wheels.
Rollerskating and rollerblading are two popular forms of skating. Learn more about skating and find links to skating equipment manufacturers and other sporting goods stores.
