All good questions, and yes, I roll that knee inward. So, boots are canted, I have custom footbeds, cuff alignment is set up (although I am not afraid to play with it more.) My bootfitter is BFs shop owner, so he spends a good amount of time, watches video of me, etc. He's brilliant, truthfully. That being said, there could still be issues there. I also attribute it to my knee injury almost 4 years ago that has made my right leg weaker, and the LCL in that knee is torn, too. My right turns are vastly worse stem-wise, as the right leg sneaks out in front of me on left turns. I have to focus on standing up over that leg and keeping it under me, and also not allowing my left shoulder to rotate back.
I am also working on releasing edges sooner, rolling that soon-to-be inside knee OUT deliberately with some drills that BF has me do. I do get aft when entering turns, too. (So much video, it's so helpful and so depressing!) Getting more weight on the outside ski, squaring shoulders. So many variables, it gets overwhelming.
