Volkl Supersport Allstar Skis and Motion Bindings- What makes an Allstar? Versatility at the highest levels of performance makes an Allstar. Volkl has added two sheets of titanium to the Allstar for even more stability. No one will catch you on those early morning groomer runs. The Supersport Allstar has the Marker Motion System. Motion systems work by allowing easier, more round ski flex. With rails or an internal interface integrated in its construction, the ski allows a Marker binding interface to glide, held in place by a high-carbon steel pin. Easier flex means even, balanced edge pressure to the snow surface. The result? Better control through precise pressure distribution over the length of the edge, and better performance.
