Rollerskates are a popular choice for recreational and competitive activities alike. However, there are various other terms used to describe them. One of the most common synonyms for 'rollerskates' is 'quad skates'. Quad skates are identified by their four-wheel design with two wheels in the front and two in the back, giving a stable ride while allowing for quick movement. Another term occasionally used in Europe is 'disco skates' since they were mostly used in dance clubs during the 70s and 80s. 'Art skates' or 'figure skates' are specialized types of quad skates used in competitive roller figure skating. Finally, 'inline skates' have a different design, with a single line of wheels in the center and are more commonly used for outdoor activities like parks and trails.
