World Cup, Euro Cup and FIS Racers do try to increase their leverage over the skis. But concerning the safety of these Athletes, the FIS has made maximum height regulations (see below). The advantages of racing interfaces like the PISTON CONTROL SL or GS INTERFACE are: Cushioning of hits and vibrations: the ski can glide faster. It is less likely that the boot touches the ground and the skier loses control. Sensitive edging for precise high speed turns. Better leverage: better pressure on the edges for icy slopes. Free-flexing of the ski
