I know this sounds silly, but maybe you can ask your feet what they need/want? Sometimes if I think too much about my body, I can't figure it out, but if I talk to it, I stop overthinking, and can figure out what I need to do.
Are you saying that one of your feet, the toes point out farther than the heel? Or the other way (the toes point inward)?
Sometimes its not just that your muscles are weak, sometimes some muscles are too strong. The strong muscles pull on the weak muscles, and the balance is bad as a result.
I hope your feet feel better!
