I'll admit, I have nothing technically to add to this thread, but wanted to chime in and say I find it all really interesting. It's amazing how such a small part of someone's anatomy, tiny technical offset or minor equipment nuance can cause such a large struggle.
It's threads like these that I also read and think...wait...do I do that? haha. Maybe I shouldn't overthink it, but it's in my genes, there's no changing that now.
Your skiing is absolutely beautiful, and looks just as functional with everything you tackle, so I don't think you have anything to worry about!!
I don't care how my skiing looks per se, it's more that I still didn't feel quite comfortable balance wise in my setup by the end of last season. Things got SO MUCH BETTER when I took those heel lifts out, but something still just felt off and I just couldn't put my finger on what it was. So, this may be grasping at straws, but since my right knee tilting in and blocking turns to that side in chopped up snow and bumps came up on my last day last season in a private lesson, it seems like as good of a place as any to start this season for a focus on technique or my stance overall. Then there was this alignment issue brought up by my fitter last year too, so might as well move that as well to start in case they are related at all. I'm so looking forward to having so much more time to be on snow this year than the last couple to hopefully work stuff out. (probably just in time to need new boots in a season or two lol)
I'm guessing you have an imperial hex set? Most boots will be metric since most ski brands started in Europe. From a quick Google ...looks like a 3 or 5 mm...

(looking at your picture, it looks like a Lange?)
Well embarrassingly I cannot find my set (probably packed away somewhere), so I was hoping to find a random one lying around.. I did find multiple, just not the right size, haha! Thanks for this, now I know what I need if I need to pick something up, I should certainly have this sort of thing tucked away in my ski bag for random tinkering in general!
My boot is a Lange, and what you attached looks to be spot on. Notice that my boot seems to be in the exact opposite alignment as their recommendation for knock knees. Mine seem to be set for someone who is bow legged, which I am most obviously not.. Weird.
I do remember someone else on a different thread who I think had issues with her boots changing positions in this regard because the screws didn't lock or something? Sounded like hers were a very specific case and known issue for her size and brand of boot though, and I assume mine have not moved on their own as I've never heard of that with these boots and a lot of people here have them. ?)
