To clarify a bit, I believe Lou is referring to "delta angle" when he said to add toe lift outside the boot. Remember we generally agree that "ramp" angle is created inside the boot and "delta" angle is created outside the boot by binding stand height differentials and boot sole lifters.
Decreasing the net forward lean inside by using heel lifts, and/or straightening the shaft via shin plates, etc., will better accommodate the lack of dorsiflexion and allow good heel contact with the boot sole for sure!
These adjustments may then tip the hips a bit too far forward, as Lou stated, for optimum balance causing the skier to shift the hips aft to compensate. If this is the case, you may need to adjust the delta angle between the boot and binding to bring the balance point back where it needs to be.
This is why working with a fitter who understands all these relationships is important as changing one parameter to solve one problem may require adjusting some others to optimize the set up.
Hope this helps to clarify?!
