However.....you have all the symtoms of Plantar Fasciitis. No, your Vibrams didn't cause this, although if you didn't give yourself enough time to slowly transition from a healed shoe, that is quite likely the cause. I usually suggest that people start out wearing their new Vibrams only about 15 minutes the first day and very very slowly increase the time over several weeks. And that's jut walking in them! Only after several weeks of walking in them would I suggest running in them, and of course I'd do that very gradually also. Vibrams are fantastic for your feet, but if you've worn shoes your entire life, many of the muscle tissue and tendons in your feet are that of a veal calf, and need to be gradually strengthened.

Walk in and tell them you want custom orthotics for Plantar Fasciitus. Bad news is they're not cheap. They're a couple hundred bucks, but they work and they work quickly! Don't let them talk you into both sets of orthotics unless you have the cash. The main set is all you need to heal. They must be inserted into a non-arch tennis shoe, so you might have to get a new pair of shoes also. I recommend the New Balance, which they sell right there. They will try and tell you that your Vibrams caused this problem because they know you can't put inserts into Vibrams.....hence they don't make money. I would let the Vibrams rest for a few weeks until you're pain free, then SLOWLY transition back to wearing them.
Don't waste your time rolling your feet around on frozen water bottles or tennis balls because it will provide very little temporary relief. The boots you wear at night are expensive and don't work very well.
