I?m afraid I have to clarify this position and respond to your denial.
First, it is pull the inside foot or boot or ski back, not the inside leg.
Second, inside ski tip lead is not the issue here.
Ideally yes, one would like to keep the tip back and even (lined up) with the outside tip, (as a visual or movement idea) just as you would like to keep either the boot, ski or foot back, as they are all connected.
When we ski properly, our hips are countered to the direction of travel, countering brings lead to the inside hip, of course then that side of the body will have some lead.
The issue is where the inside boot resides relative to the hip and outside boot.
Have a look at the photo to the left, the inside boot is back and there is little tip lead noticeable at this angle.
If it is not pulled back, and if there isn?t some tension to hold it back, it will sneak forward and the skier will end up with hips low and back. This is just plain fact, I?m sure you will find after you use, train, and research this possibility you will find a great advantage to your skiing.
Enjoy the books and video, Merry Christmas to all.
