I just offer this as a thought because it goes against conventionally accepted procedure. Sometimes the body needs to be allowed to fix itself, but you have to give a chance.
I had a bad case of plantar fasciitis a few years ago and followed the orthotics and stretching route to get rid of it - and that took over a year. I still had other problems with my feet, though, caused by wearing boots that didn't fit right, even though I still used the orthotics.
What I finally discovered was that I needed to strengthen my foot muscles and tendons rather than support them (you can't learn to walk on a leg that has been broken if you keep using crutches).
I started a regimen of barefoot (minimalist) running in an effort to strengthen my feet. That was 3 years ago and my feet have never been healthier,and all I wear is minimalist (flat, no-heel, no arch support)shoes (moccasins) every day all day, and I'm on my feet alot.
Maybe it wouldn't work the same with a broken foot, but my wife had Morton's neuroma in one of her feet from a break when she was a child and she does very well with the minimalist shoes, also. Just saying.
