Boots used in artistic roller skating are traditionally made of leather, but contemporary boots are often crafted using synthetic materials. While there are boots made specifically for artistic roller skating, skaters may choose to use ice boots, though the use of ice boots is mostly prominent in inline skating. The style of boot varies based on the personal preference and the discipline the skate is used to skate in. In general, free skating boots are stiff to support skaters' ankles and prevent injury as they spin and jump. In the figures discipline, stiff boots are used for circle figures while slightly softer boots are used for loop figures. Dance boots are the most flexible and soft, with a low cut back for ankle mobility, allowing the skater to point their foot and create aesthetic lines with their leg. Boots come in many different brands, some of the most popular being Riedell, Edea, Risport, Harlick, SP Teri, and Jackson.
