An improved roller skate includes a shoe portion, front and rear wheels, and a bracket coupling the wheels to the shoe portion. The have a “generally”spherical shape which allows the skater to maintain a rolling surface of each wheel on the floor or ground, while leaning the skate by a relatively large degree with respect to a line extending perpendicular to the floor or ground. Each wheel has a rigid inner core and a softer outer cover. The inner core includes an axle housing connected to a hollow, “generally”spherical, rigid shell by a plurality of radially extending spokes. The bracket coupling the wheels to the shoe portion includes arms coupled to the wheel axles. The shape of the bracket and bracket arms are designed for strength as well as to allow for a high degree of skate inclination (lean or angle) with respect to the ground or floor without contacting and scraping the ground or floor.

An improved skate device comprising: (a) a plurality of wheels, each wheel having (i) an axis of rotation, (ii) a generally spherical outer peripheral shape with an indentation at each location at which the axis of rotation traverses the generally spherical outer periphery of the wheel, and (iii) a core adjacent the generally spherical outer periphery of the wheel, the core having (A) a generally hollow outer shell defining an inner peripheral surface and an outer peripheral surface, (B) an axis of rotation in common with the axis of rotation of the wheel, (C) a generally spherical shaped peripheral surface with a generally cylindrical indentation at each location at which the axis of rotation of the wheel traverses the peripheral surface of the shell, (D) an axle housing extending along the axis of rotation of the wheel, and (E) a plurality of spokes extending from the axle housing to the inner peripheral surface of the outer shell and extending along substantially the entire length of the axle housing; and (b) a bracket coupled to the wheels, the bracket having a base and at least one arm associated with each wheel, the at least one arm being connected to its associated wheel inside one of said indentations.
