Rollerblading

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.

Inline skating is also known as "roller blading" due to the popular brand of inline skates, Rollerblade.

A term used to refer to inline skates on a vert ramp, a half pipe with some vertical in it usually between 6in to 24in. Vert skating is a form of gymnastics performed with skates. The purpose of vert skating is to ride higher than the coping (which is the metal pipe on top of the ramp) and perform spins or flips. It focuses on complicated hard aerial maneuvers, such as spins and flips. The intent of the skater is to build speed until they are of sufficient height above the edge of the ramp to perform various aerial acrobatics. In competitions skaters have limited time, often less than a minute, to impress the judges by landing numerous and difficult tricks. The sport was included in the first X Games in 1995. Vert skating is used in a lot of competitions such as the X Games. Vert ramps are also present in most skateparks of today.

In addition to speed, fitness, artistic, or skating for fun, some skaters prefer to skate aggressively.
