I have had plantar fasciitis for years, on and off.  Usually only get relief from custom orthotics, and my insurance only covers them every few years.  So I was left in pain, trying all sorts of shoes for comfort.  I feel I've went through every flip flop on the market, in varying thicknesses to help alleviate the pain with a soft heel.  I read the reviews and basically bought solely on other PF sufferers.  OMG, heaven!  The thong part took a little to get used to, as its set a little further back on the sole than I'm used to.  The softness in the heel is so comforting.  I can actually walk a block and not be in pain.  I now use them in the house (no more barefoot walking!).  This has been a lifesaver!  If you've been hesitating, don't, these are going to take away the pain and get you back to walking normal again.
