Each ski section is provided with its own mounting midway between opposite ends of the ski section, the forward end of each ski section being tilted upward in a conventional fashion to ride over a snow surface. The mounting of each ski section is yieldable so that as the rider leans toward one side or the other, as in turning alignment of the ski sections shifts angularly following a turning arc in a corresponding direction.
