Lisa, I have had years of foot and back pain, although I never knew the actual reason why. One day I went into my local shoe store and they recommended Dansko shoes. My feet feel so much better since I started wearing the Dansko's. I am not sure of the PF issue though. I looked at the Dansko website and they have a few to offer, although they are not of the sleek and sexy variety, LOL. The Ryan and Risa look nice and if they are comfortable and you could wear them all day that would be a plus, LOL.
DANSKO BOOT LINK HTH
