A resounding NO!
Funny thing just happened, as I was reading this an old friend from Salomon N.A. Bill Rauscher who is the head of the risk management department for Adidas and Salomon walked in my shop. What a coincidence to be able to discuss this with him.
While we agreed on the difference between reality of binding functions and ski area's risk management reality, there is a gap that probably will not allow you to make adjustments like this with your students and be 100% risk free.
This does not however belittle the fact that these are important adjustments to be able to make!
Bill agreed that placing a 3mm shim under the heel piece of any binding would not have negative affects as long as the heel engaged the boot. The grey area is the toe. He said that placing a 3mm shim under the toe would not be an issue as far as height adjustment, the issue is the affect on friction it creates laterally. I have in the past used bontex shims without issue, but talking to Bill I may begin using the actual lifters that I plate boots with for my fore/aft shims. I will do some torque testing to see what affects there are as far as increasing release torques or not?
Your comments in this post #60 demonstrate what I see many instructors do.
They find a way to justify to themselves that assessing and correcting lateral and fore/aft angles is unimportant and therefore not worth their attention or effort. This could not be further from the truth as evident in the success of elite level racers, and instructors, and ski improvement camps such as ESA, PMTS, NASTC, etc..
I know I for one will continue helping people ski better because of my willingness to take this very calculated minimal risk. You must certainly make your own decision but do not believe that because you choose not to that it is not a invaluable benefit to skiing improvement!
