Abstract: A skating appliance or vehicle having a skate with a plastic base and a composite running blade exchangeably secured thereto. The exchangeable composite running blade is secured with the high resistance to torsion and flexure as well as high security against fracture, by means of an on edge mounted profiled stabilizing rail set into the lower side of the base, and easy to handle screwable holding members, and a corresponding design of the individual parts. These elements allow an arrangement to be obtained which as a whole has a low weight and a high resistance to pressure.
