Abstract
A multi-function roller skate system functions as a conventional skate configuration, with the wheels wide apart, and also as an in-line skate configuration, with a single row of wheels. The skate has multiple pairs of wheels which may be moved closer together or farther apart according to the skater's needs, either in connection with training or to accommodate changing skating conditions. When the wheels are at their closest, each pair operates as a single wheel directly under the skater's foot like an in-line skate. The skate may include at least one intermediate position for intermediate skill skaters. In addition, the skate may be extended to fit different or growing skaters.
