I am going to describe the sequence of a turn. I will leave out the secondary movements like arm position and counter. Remember that all movements start with the feet; the base of the kinetic chain.
Release: Lightening of the new free foot. This tips the CM into the new turn. The resultant tip of the CM transfers to the new stance ski and causes it to tip without input from the skier (stance ski is passive throughout the turn).
Transfer: The weight is transfered from old stance ski to the new stance ski. At this point the new free foot is brought in and under the hip, or heels together. This enhances balance on the stance foot and allows a more aggressive tip of the free foot.
Engage: All that is left is to engage the stance ski. This is done by tipping the free foot to it's LTE. Turn shape is controlled by the amount of tipping. Also, this is where secondary movements come into play.
Note that I have only described movements of the feet. Other movements, such as the CM moving into the turn, are a result of a movement of the feet.
