Abstract
Abstract A roller skate in which plate-like members having means securable to the foot of a wearer, are longitudinally slidable along a guide rail. The mounting members for the roller pairs are also longitudinally slidable in a recess in the bottom of the guide rail and the plate-like members and the roller mounting members are securable at a desired position along the guide rail. The plate of an ice skate may alternatively be inserted in the recess in the guide rail.
