Abstract
In sport equipment in the form of short ski-like rollers for each foot, with a support as base for the shoe of the user and only one front wheel and one rear wheel each, a particularly compact and maneuverable construction of the equipment is achieved owing to the fact that the front wheel and the rear wheel and their axes are disposed within the longitudinal extent of the support.
