(Not to be confused with Vert skateboarding.) Vert skating or vertical skating is a discipline of aggressive skating in which inline skates or roller skates are used on a vert ramp, a style of half-pipe. In vert skating, the skater is able to achieve more air-time as compared to other styles of aggressive skating, meaning skaters can perform complicated aerial maneuvers and acrobatic tricks, such as spins and flips. Vert skating is considered a challenging sport: as of 2012 there are fewer than 15 professional vert skaters attending competitions.
