The sidecut consists of a smaller turn radius in the tip that works that in conjunction with a larger turn radius in the tail, creating a directional ski that is stable going straight, but will easily carve once the turn is initiated and the ski is on edge.
The rocker profile and tip shape are combined into one progressively changing elliptical arc, which allows the tips to plane faster in powder, deflect less in variable snow, and helps the effective edge running within the rocker length to engage in a more natural, effortless way.
