They are one of the few things to have helped me over the long term, so I highly recommend them now. Glad you too are finding them supportive, helpful shoes. I have been trying to knock out this PF condition since summer of 1998 -- and I am now at the point of again being able to walk just a little, a mile or so per day, which for me is real progress. I credit a lot of my improvement to Birkenstocks and expect I may be wearing them for the rest of my life -- which is okay by me. My feet feel terrible in other shoes where I don't have the Birkenstock support.
