Aggressive inline skating is an extreme sport, performed on specially designed inline skates with a focus on tricks and stunts. The sport mainly consists of a wide variety of grinds, aerial tricks, slides and other advanced skating maneuvers. Participants often refer to the activity as rollerblading, blading or rolling. The sport is divided into vert, park, and street skating, referring to the environment that is being skated in. Different environments lend themselves to different tricks, thus the distinction.
Tricks in aggressive skating can be performed on street obstacles or on ramps. Street skaters perform more grinds and slides, whereas ramp skaters have more air-time and therefore can perform other tricks. Many of the aggressive tricks are similar to those done in skateboarding. Skaters can perform grinds by using the the frames and plastic plates on the bottom of the aggressive skates. Grinds are usually done on rails and ledges although they can be performed on any obstacle which slides.
