A in-line roller skate has spherical roller wheels with multi-directional turning ability. The skate has the ability of both forward and rearward movement, but can also slide sideways in lateral and angular directions, in a similar manner to a figure skating ice skate. The roller skate achieves the versatility of movement of figure skating ice skates. The skates include a single line of spherical shaped wheels, which substitute for the single axis wheels of a roller skate. The roller skate can slide sideways. In use, the roller skate provides a skater with multi-directional movement, such as forward and rearward movement by the rotation of roller wheels in any direction. Because of the multi-directional movement of the spherical roller wheels, the skater can rotate and spin about a vertical axis like an ice figure skater, as well as slide sideways.
