Quad skates have wheels that are arranged in a two-by-two configuration. This makes them more stable, and therefore better for beginners. Quad skates (or roller skates) are the perfect choice if you are interested in dancing on your skates (such as with artistic or jam styles) or if you are interested in roller derby.

Modern roller derby is an international sport, mostly played by amateurs.

The general rule of thumb is to choose a plate size within one inch of your boot size. For example, if you wear a size 8 skate boot, you'll want to choose a plate size between 7-9 inches. In conclusion, finding the right size for your roller derby skates is crucial for optimal performance and safety on the track.

Roller derby is played on an oval track. Players called “jammers” attempt to pass groups of players called “the pack.” This involves somewhat simultaneous defense and offense, resulting in a great sport to watch. Roller derby is a full contact sport played at a break-neck speed -- on wheels.
