A wheel for inline roller skates to allow oblique and lateral rolling movement includes an annular hub for mounting to axles associated with the roller skate with the hub having a circumferential groove formed thereabout with the groove being defined by curved wall members extending radially away from the central hub body and curving inwardly toward one another with a plurality of spherical roller elements fitted within the groove and extending circumferentially about the central hub body for free rolling movement within the groove with the roller elements being retained in place by the walls and being free to roll in any direction, thereby allowing a roller skater to experience oblique and lateral motion.
