Steering a turn, while using a small skid angle.  In a small skid angle, the skis deflect and point only slightly away from the skier’s actual direction of travel.  Narrow track steering leaves a very narrow skid track in the snow, and thus does little to reduce speed.  When done skillfully, casual observes may have a hard time distinguishing it from carving.  It allows for a wider range of turn shapes than carving provides, while avoiding the higher steering forces and speed loss of wide track steering.
