I think of this way of doing transition as making "overcompleted turns." I maintain old edges as long as possible, and bring both feet back up under me to end the old turn. Feet travel in a sideways figure eight beneath the CoM. When the feet get back up under enough, the body topples, the edges change, and the skis start to move downhill.As described in the video is precisely how I ski. I do not use a traditional 2-4-2 turn transition. I steer in the direction of the old turn until I am on the new edges. The bulk of my weight/pressure transfer is before the edge change. It's a default perfect turn entry. ....
....I let the skis, ski back to me, I don't let the center of mass flow back to the skis.
@geepers, in my version, don't know about Pierre's version, yes, bringing the feet back up under me involves shortening the new inside leg independently of the other leg.
Is this similar to what you do, @Pierre, or different?
