Abstract
Each wheel of an inline roller skate incorporates multiple tires, with a center tire allowing straight-ahead skating and the two side tires allowing maneuvering forces. Leaning the skate such that none of the tires makes good contact with the skating surface causes the skater to skid sideways. By increasing the roll angle, the skater engages more sideways friction of the side tires, and comes to a controlled stop. By modulating the roll angle, a skilled skater can control the rate of deceleration. An added nose wheel allows the skater to tilt toward the toe, like an ice skater, to reduce straight line contact with the skating surface, and enable curvilinear skating.
