In my case, my PF was due to an injury. I knew it the instant that it happened, and I could barely walk for a couple of days. Lots of collagen, stretching, massage, and time cured it 100%.
If you have chronic PF, then something is irritating the fascia. In that case, you have to figure out what is doing the damage and eliminate it. There are good suggestions in this thread: arch supports, orthotics, stretching, and maybe not low-drop shoes, at least until you can get accustomed to them.
It is possible that transitioning to low-drop over time could help, as well. In that case, you might try wearing low-drop shoes at home, and switching to something more traditional for the trail?
Are you sure that your heel pain is caused by the fascia? If it is just heel pain, then there could be another cause. Do you get the same pain when wearing high-stack, more robust, shoes or boots?
