Abstract: Disclosed is an in-line skate wheel that includes: (a) a braking portion including a high friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.45 to about 1.5; and (b) a skating portion including a low friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.1 to about 0.45. The skating portion includes a higher proportion of low friction surface material than the braking portion. The wheel delivers variable traction in response to the angle of wheel contact with the ground, without sacrificing a smooth ride or wheel durability. Utilizing the variable traction of the wheel a skater can stop safely and reliably, using known ice-skating maneuvers, wherein the wheel is turned away from the skater's direction of travel.
