Quad Rollers by the company Athlopaidia. Quad Rollers are the classic four-wheeled skates, with two wheels in the front and two in the back, and usually a rubber brake in the front. They feature a wider base, which offers even weight distribution, while their wheels are wide and flat without edges. This makes them more stable and possibly preferable for amateurs. You can easily maneuver by slightly shifting your body weight to the right or left. Suitable for even surfaces, they offer manageable speed in a straight line but are not ideal for those who want to move at high speeds. They help in gaining confidence, learning balance, and developing control. Their design puts less pressure on the ankles.
