    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.

    Abstract: A skate wheel for an in-line skate has a skate wheel hub with an inner hub, an outer rim, and a plurality of blade-form spokes extending therebetween, and a skate tire mounted upon an outer surface of the skate wheel hub. Opposed surfaces of adjacent spokes, in cooperation with opposed surfaces of the inner hub and outer rim, define airflow passageways through the skate wheel. Each blade-form spoke has a radially-aligned first spoke-edge surface exposed at a first face of the skate wheel, a radially aligned opposite, second spoke-edge surface exposed at an opposite, second face of the skate wheel, and a blade-form body extending smoothly therebetween. The first and second spoke-edge surfaces are offset in a direction of travel of the skater by a predetermined arc of rotation of the skate wheel and hub. Also described are in-line skates with skate wheels of the disclosure, and skate wheel hubs for such skates.

    Abstract: Shoes with various configurations of rollers secured to one region of their soles for rolling, while leaving another sole region exposed for walking. The rollers are mounted to rotate about an axle defining a primary axis of rotation extending at an angle of between about zero and 45 degrees to the walking direction, as viewed from above the shoe, for rolling sideways along a support surface. This provides a combined running-rolling method of locomotion, by running on the exposed sole surfaces, and then jumping into a “surfing” stance for rolling. In some cases, the rollers are mounted on steerable truck assemblies. One particularly small truck assembly includes wedge-shaped bushings for steering compliance.

    Abstract: An in-line wheeled skate which includes one or more rollers located between the wheels and above the ground plane, thereby enabling the skater to jump up on a rail (or other supporting surface) and roll down the rail sideways, as in `extreme skating` maneuvers, by placing the skate on the rail with the rollers bearing upon the rail surface. The rollers may be, for example, cylindrical or spherical, and are preferably located between left and right side planes of the skate wheels.
