I had it in my left foot several years ago, and the podiatrist sent me to a physical therapist, who said the problem was a tight hamstring. We did various exercises, and I also started replacing the insoles in my shoes with SuperFeet, which I bought at the store that provides my tennis shoes. The plantar fascitis eventually just went away, and I had no problems until recently, when I developed it in my other foot. I have gone back to doing the exercises, and made sure I have new SuperFeet in my shoes, and it seems to be improving on its own. I always wear supportive shoes, even when I am sitting around the house. Despite the discomfort, I have continued to play tennis, and I often don't even notice the pain when I am playing, so I am convinced that the leg exercise is the most important factor in correcting the problem. I always have more pain when I get up in the morning than I do after I have been moving around for even a few minutes.
