The next step is to match the angle of your boot cuffs to your lower leg angle standing on your properly posted footbeds in the shells. Lastly you would have your sole canting assessed to see where your center of knee mass plumbs over your boot and if needed the boot soles planed to the appropriate angle, lifted then routered to DIN specs! This is just the frontal plane and you should also have your sagittal plane assess and adjusted if necessary as well.
The fastest easiest way to improve ski performance is to have your equipment properly balanced.
I can honestly say that I don't think I have ever been in a good neutral position. I had one bad experience with footbeds when I was a snowboarder. And it kind of scared me off. My fit is good on my current boots, but I've never been able to get in a real relaxed position, and no matter how fit I am it gets taxing.
I have come to realize that I over supinate while walking and running. Causing me some issues over the years. I'm sure this carries over to my skiing.
Hopefully my local fitter can get me where I need to be.
