An unusual occurrence: I think I pretty much agree with your perspective on why the boot flexes in your recent posts.
I'm going to go with "managing forces" .
Like the word "turn", I think "absorption" might be one of the most miss-used terms in skiing. How many times have we heard to control speed in the moguls using absorption? Nonsense! …if you perfectly absorb a mogul then it will not effect your speed! If Hirscher absorbs the forces in the turn then they are not transmitted to the boot, thus the boot does not flex.
The boot is flexed at the bottom of the turn though! And at the same time, Hirscher is flexing from 5 through 7. Hmmm…
He is using the deflection/impulse/centripetal_force (however you care to express it) from the skis/BoS and vaulting (if that needs called out) to accelerate him on a trajectory (across the slope, down the slope AND up away from the slope) toward the blue gate. While doing so he is standing against a ton of force and the boot is helping to support him (and it flexes under the pressure as it carries some of that load for him - should we say the boot absorbs the turn forces to help confuse the absorb issue?) He is balancing both the amount of absorption and how much he resists (or does not absorb) - managing the forces. Yes, he is flexing as he comes through the bottom of the turn, but he has not gone completely limp - nor has he completely absorbed all the turn forces; he is still supporting a tremendous load on the leg even as it flexes and the boot is there to help support/carry the load.
So, I see him coming around the Red gate and driving powerfully toward the Blue gate much as someone doing a standing long jump from the Red gate to the Blue gate might do, even though he is flexing at the bottom of the turn.
If one was to do that standing long jump, what joints would they (not) use and how would they get their feet from behind them at the red gate to in front of them landing at the blue gate?
Time to get the snow tires off…
