I’ve suffered from some of the same issues/symptoms. Have a pin in my right hip from when I was young which made my right leg slightly shorter than my left. Add in a broken left ankle 15 years ago and a broken left foot 7 years ago and my internal muscular canting is a little off. I get that hooky tip feeling on my left inside early season until I build the muscle back up. I’ve had to do a stretching/muscle building routine working from the feet up.
before I get deep into what Ive done maybe try something to see if we are on the same page.
With legs spread shoulder width apart and feet in a neutral position see how hard you can push your right Big toe into the ground without flexing your knees or leaning foreword. Then try with your left toe and see if you can push as hard as with your right without leaning foreword. Then sitting down Try to independently bend your toes in a bunch of different directions. Can you do the same on both feet?
For me it had something to do with the tendons/muscles In my ankles and how it controls my toes. When I’m unable to pressure my left big toe correctly I’ll compensate by putting too much pressure foreword on my boot to try to use my ankle to really get pressure on my big toe which can slightly puts me out of balance. New liners or footbeds feel great right away but will break in kinda wonky if I don’t build strength in the muscles independently of my ski boots.
