frame 1 - i'm "forward", but the tips are coming up, weird, right?
frame 2 - i'm "back", tips up.
frame 3-4-5 - no pressure, no snow spray, just pulling the boots back (although it looks like i'm pushing them away, I guess I'm doing both, we need 3D goggles), gliding and tipping, tips are (leveraged) down so they start the carve.
frame 6 (time compressed) - hello, pressure is here - clearly on the tips. yeah, I see I "landed" on the inside this time whatever.
frame 7 - ski and boot get the snot bent out of, without breaking a sweat or doing anything special - i was clearly reaching for a coctail
NIce turn sequence razie. I do not think you are 'back' at frames 1 and 2.
I think you are just down-unweighting into cross-under and your feets are continuing their arc and your COM is moving inside the new turn.
You can't apply shin pressure here unless you pivot the skis across your direction.
Down-unweighting is cool and give you lots of options about how to go into hook-up... including anticipating for some knee action to get more edge on to influence the arc before pressure builds...
And You know you are going to hook-up.
Then in frame 4-5 your legs get long to follow the ski and as they get long; they have moved outside your COM track.
So yer stacked as the skis cut off your COM's track; pressure builds and you crush the front of the boot and the ski bites big-time. This crush is a result of Arc and COM. Not a conscious goal to influence ski performance.
At this point I like to face more out-side and drop my butt and increase the edge angles even more.
So many posters in the thread are thinking only one dimensionally... along the ski - rather than across it.
Think 2-D: The ski builds pressure on the feet when it crosses your mass-track.
If you're in-tune with these arcs you don't pull your feet any way but towards you to availementi or absorb some lumps.
You Stay Centered. The pressure on the cuff comes ON into and out of the falline and gets massive across the hill.
this shot for me is of someone about to Exit a turn. The legs are bending/bent and absorbing the pressure generated in a turn just before turn-exit.
If this person had bent legs like this in the fall-line and tried to generate more pressure; then t'is bad stacking.
" your legs are long when they should be short' ... and when they should be short and you are long... you are high-siding.
Rigth on zentube and cgeib.
