I wouldn't have a clue as to where he could get footwear.

I purchase "over-sized" footwear (extra length and width), and can get by with that, but the swelling on your husbands foot and ankle is to such a degree that regular footwear almost assuredly won't work.

What does he currently wear? How well can he walk? Is your husband seeing an actual podiatrist, or can he see one? I realize the limitations of workers comp, etc. but I am wondering what a good podiatrist that is versed in CRPS would have to say about his condition. My podiatrist is the primary physician for my CRPS, and I would be lost without him.

Yes, this is a good forum for information and sometimes to just "vent" as people and families of people with CRPS, or any chronic pain condition, go through so very, very much. Welcome to the forum.............
