Excellent thoughtful analysis as always. I need to do something similar.
I tried on and almost bought the TAOS Craves in burgundy in November. I suspect they may be wide for you if I liked them, but laces and inserts may make them adjustable enough. I can’t remember if I sized up - I’m typically a 37 or a 6.5W or 7M. I have an ancient hard translucent plastic 3/4 custom orthotic that fit well in them.
Have you looked into custom orthotics? The materials and styles have come a long way. I definitely flare my PF if I don’t wear mine! Which are 30+ years old.
