I just found this forum and your advice to help others is refreshing.
I have been having a problem that has been plaguing me for years. I changed boots about 6 years ago and that's when things went bad. I had a pair of Technicas that had a heel lift under the liner as I have limited dorsiflexion. They also had a 2 mm toe lift outside of the boot. It took quite a while to get this all figured out, but in that configuration my fore aft alignment was pretty good.Subsequent to the Technicas, I have been through a pair of Heads, Nordicas, and Rossignols with terrible problems with fore aft balance - to the point of falling over backwards. I currently am in a Dalbello model with a small heel lift and for whatever reason I am much more balanced in the fore aft plane then in the previous three boots. But maintaining balance is still a struggle. Even just getting off the lift or skiing an easy green run I can find that sometimes I simply cannot keep my ankles flexed and stay in shin contact with the boot. It is terribly frustrating. I tried both an external heel and toe lift under the boot but that really doesn't help at all. After trying lots of combinations I find a small heel lift under the liner together with softening the flex (adjustable on the Dalbello) has benefited me the most. I have taken several lessons and instructors have observed the problem but no one can clearly identify what is happening. Realizing that this is tough to diagnose, has anyone else had a similar issue and if so, what boot modifications or suggestions might you have? Thanks for any help.
