I was in a ski shop today discussing a heel lift for my wife - a level 1 instructor- in order to get her "more forward". He did a demonstration with my wife and my 14 year old daughter -J3 racer- how if he raises their heel and they flex forward, their butt will compensate by dropping back and outside of the invisible line above theri ankle. He then put a lift under their front toes and when they flexed forward, and their hip remained aligned with their ankle. A race coach noted that if you put the heel lift in, you create a gap at the back of the boot that needs to be filled between the shell and the liner. I have spoken with two boot fitters and one race coach and have three different approaches/ideas. I would like to break the "tie" and find the best method for offsetting women's natural back-seat tendency.
