I had plantar fasciitis for a long time until I discovered that if I wore boots that were wide enough in the front so that there was no side pressure on my toes or the ball area of my feet, the symptoms would go away. This was not easy for me to do, because if you trace my feet, the result looks something like a ping pong paddle: wide in the front and narrow in the back. So if I just went extra wide in a normal boot, my heels slid around and I was just substituting one problem for another. But I finally managed to find a few brands of boots that worked, like Keen. None of the brands I found were super high quality, but they fit well, so I just had to replace them more often.
