Rolfing is deep tissue massage, working the fascia itself and loosening any adhesions/stuckness so that you can move easier and stand straighter - kind of like chiropractic, but working the fascia instead of the bones.
Ida Rolf was the "founder" of it - thus the odd name.
It hurts like &%^$&*% usually (a colleague of mine calls it "a joyful pain"), but feels so much better after it's done and has made a world of difference for me, especially my feet. I have been PF-free for several years now, after a few sessions of rolfing, and can even wear mostly "normal" shoes (but still don't like to go barefoot for very long, even at home).
I should mention that I did go to a podiatrist for months after living with PF on and off for a few years. I did the ice, nighttime "boots," Aleve, orthotics, etc. etc. and after a few months, it was back. That's when I remembered another Rolfer had given me some relief a few years before and went to a different Rolfer who was closer to where I live now, and after a few sessions, the PF was gone - and I had better posture and other problems were going away. I haven't been in over a year (I miss it), but went faithfully every few weeks for 3-5 years, even though my insurance won't pay for it.
