Now, lets look at what just inside leg extension does. As you extend the inside leg (without retracting the outside leg) the center of mass rises as you cross the skis. If you are watching, you will see both legs are long at the cross over point and then the new inside leg starts to retract during the turn.
Depends on the type of ILE used. There are many. One variety may see both legs fully extended at edge angle neutral,,, another will see old outside leg flexion happen as the skier transitions to neutral. It all depends on how much you extend, and it only takes a fraction of an inch to make ILE work.
Yet all ILE variations will see a rise of the CM on the way to neutral. Even with no extension of the old inside leg the CM will rise because of the penduluming process. Only in very strong retraction transitions does the CM not rise.
Comprex, the biggest difference between a pedal turn and ILE is that the pedal turn generally includes a pivot, and ILE transition generally does not.
