sorry late to the party here.

I am in agreement with the neurologist. Disagree with saying these statements are wrong or too general; If you can't be specific in your comments Jim then please clarify.
For the OP: Trace an outline of your foot on paper, then take footbed out of shoe and overlay it on the drawing. Footbeds are not any wider than the hard sole of the shoe be it carbon or nylon.
It wouldn't hurt (so to speak) to consult podiatrist to eliminate possibility of neuroma or sesimoiditis as you've had this issue for quite some time.
take those wedges out they're probably not doing anything anyway.

Here is a small selection of feet and shoes that don't fit - all of these people had numbness or hotspots, had tried moving cleats everywhere to no avail.
