Each roller skate consists of a plate (1) for a foot rest with a fastening (2) either for the skater's boot or for his foot. Two or more rollers (3) are fixed to the lower face of the plate in a single row along the skate. The axis of the leg also passes through the central plane (4) of the rollers. The dimensions and shape of the tyres on the rollers are adapted to the ground and can be changed accordingly.
