Is the infinity move a MOVE?
I view it more of a consequence of everything else working right, which would require a lot of words to describe here online.
It's something I try to be aware of through proprioception.
Fine-tuning one's awareness of the whereabouts of body's center of mass and the feet is required in order to sense it happening.
But an action, a movement? Not in my worldview.
Interesting question, but to me, the infinity move is something I actively do. To me, the start of the next turn is a "consequence of everything else working right".
But I am (trying to) actively drive that outside ski around while opening the ankle a bit to allow the COM and the skis to cross paths. If I didn't do something,my ankle would remain closed. I could still release the edges so that I'd be in neutral (laterally speaking), but I wouldn't be in a position to allow the "x move" to occur... And without an X-move, I've learned that the next turn is gonna suck.
With that said, I'm looking out the window and it's snowing, so it's time to stop typing and time to go skiing.
