Sliding movement is replaced by a flexible track which is guided by the wheels' air bags. The flexibility of the air bags and the track absorb bumps in the ground. The skier is held on the ski tips by the ski boots. There is a fixed stop at the front and a lockable stop in the rear. Two bearings of the brake stop, comprising two metal rods, are screwed either side on top of the platform.
