The faster you go, the more you can lay it over and push your feet away from you. When you can get your hip into the hill and have a strong platform on the outside ski, you stay balanced. The key to a good turn is a confident initiation: pull your outside foot back so your tips don't dive into rough or deep snow. Let your skis—not your shoulders—swing across the hill. On firm snow you need to lead a with your inside arm to keep your tails from breaking loose. Soft snow is a bit more forgiving.
