I have suffered with this same problem and it really just takes lots of good shoes that are more or less orthotic, stretching the calf muscles with a yoga strap pulling the toes towards you as best you can. I also would wear a special boot at night that helped to keep the toes straight and the foot flexed. Good luck. I can't wear flip-flops at all and I live in Florida. If I wear them for only one day the next day the PF starts right back up. Be patient, it does take some time to recover from. Also do not walk on the floors in your house barefoot, make sure you have good support, no bare feet! Sorry ( most comfortable):
