An in-line roller skate includes a frame having a pair of parallel, spaced side rails. At least one and, preferably, a plurality of ball rollers are mounted in the frame between the forward and rearward ends of the frame. Each ball roller is mounted to the frame for unidirectional movement by a base attached to the frame. A concave bed is formed in the base and is substantially covered by a plurality of rotatable bearings. A cap having a central aperture in an end wall is secured to the base and encloses the bearings and the ball roller, with a portion of the ball roller extending through the central aperture in the cap. In another embodiment, an axle is centrally located in the frame and extends perpendicularly through the side rails and rotatably supports a cylindrical wheel thereon. Ball rollers are mounted forward and rearward of the wheel depending on the location of the wheel in the frame. The frame is fixedly attached to a boot of a sole member with a plurality of straps with closures mounted on the sole member for releasably attaching the sole and the frame to a foot of a user.

An in -line roller skate comprising: a frame having a top, an open bottom and a pair of parallel, spaced side rails extending forward and rearwardly between opposed front and rear ends; means for attaching the frame to a boot; an axle mounted in and extending between the side rails and between the opposed front and rear ends of the side rails; a wheel rotatably mounted to the axle for rotation about the axis of the axle; a pair of longitudinally spaced front mounted ball rollers disposed forwardly of the wheel and mounted in the frame for unidirectional movement; a pair of longitudinally spaced rear mounted ball rollers disposed rearwardly of the wheel and mounted in the frame for unidirectional movement; the pair of front mounted ball rollers, the pair of rear mounted ball rollers, and the wheel being mounted in the frame such that a surface contacting portion of each is co-planarly arranged along the frame; and ball mounting means for rotatably mounting each ball roller of the pairs of front and rear mounted ball rollers to the frame, the ball mounting means including: a base attached to the frame and having a concave bed formed therein; a plurality of bearings rotatably disposed on the bed and covering substantially the entire surface of the bed; and a cap removably mountable over the base, the cap having an aperture formed in an end wall; each ball roller of the pairs of front and rear mounted ball rollers rotatably engaging the bearings in the bed and having a portion thereof extending outward through the aperture in the cap.
