I believe, A boot that puts us in a statically balanced position with our skis on, by achieving the appropriate angles for the individuals morphological needs will inherently require very little ankle flexion to maintain dynamic balance. In fact a stiffer boot will reward a more skilled skier who uses the leverage provided to maintain his/her balance.
Should our equipments angles be less than ideally adapted to our needs the skier will find a softer flexing boot easier to use because they will have to move to a better position to balance effectively than the boots/bindings statically place them.
Certainly a less skilled skier will need a softer flexing boot to absorb unanticipated shocks, accelerations and deccelerations, and gross adjustment of their cm. to regain balance. A more skilled skier will detect and correct imbalances sooner and anticipate balancing needs better so therefore will appreciate a more responsive boot provided it's static placement of the foot and lower leg is optimal.
This is why fore/aft assessments and adjustments are critical to optimum balance. Granted there are many variables, some of which were eluded to in this thread. Ranges of flexion, length of tib/fib vs. foot length, boot ramp, binding stand heights, height, weight, etc. all work together to determine where we need to be. If you think a random choice in boots and bindings will put you in the optimum position out of the box, your chances are slimmer than you think!
