@mietzel– Hi. I'm up for some foot surgery on the 13th of August. I've never gone to a podiatrist before but he's already told me what I will need for footwear. Perhaps someone else will have ideas but your doctor should be a great source. The trouble is everyone's foot is so different that it's difficult to recommend what would fit you.
Have you considered having the bunions operated on? Was this suggested at all?
