I purchased a pair of Fitflops based on the recommendation of a friend.  I now have 5 pairs.  My favorite by far is the Pietra, I have lived in these sandals all summer.  I have the black and the bronze, and have just ordered another black pair as a spare!  I thought I was through wearing sandals due to plantars fasciitis...but these are so comfortable, give great support and I have not had any foot pain.  Amazing!!  I can even wear them to walk the dog.  I have 3 pairs of Pietras and 2 Walkstars.  This Pietra is less clunky looking and I had to order up (I wear a half size) not down as some other reviewers have said.  I also like that the soles are black, I have not ordered the pewter or the silver only because of the white soles.  These are pricy for a fipflop...but worth it.
