On a "rocker" ski, the tip, and sometimes the heel, comes off the ground much sooner than with a cambered ski: this has the effect of moving the contact points toward the centre of the ski. The surface of the ski in contact with the snow is shortened and offers manoeuvrability and lift in soft snow. When taking corners, the edge length provides more grip on hard snow. The longer the rocker, the better the handling of the ski.
