ABSTRACT:
A roller skate includes at least one front roller, a middle roller longitudinally aligned with the front roller, and a pair of rear rollers. The lowest point of the front roller is substantially higher than the middle roller and the pair of rear rollers to that a skater can skate only with the front roller and the middle roller. Alternatively, a hinge member connects pivotally the front portion and the middle portion of the roller skate so that the pair of rear rollers can be lifted up, thereby, allowing the skater to skate only with the front roller and the middle roller. In this way, the skater can gyrate smoothly at a radius smaller than that of a conventional roller skate.
