I bought my Fitflop sandals from you after seeing a magazine ad.  I found that your lower price and free shipping was just what I wanted in order to try these sandals in their original form.  Then I was notified by the actual vendor that they hadn't shown that exact sandal in the ad and would I take a $10 credit with their apologies.  Of course I would!  SO now I have been wearing them for a few weeks and I love the way my feet feel in them.  I am pretty sure they are working my muscles because I am getting hamstring cramps when I do weightlifting exercises for hamstrings. I guessI will just have to keep wearing the sandals.  It's a good thing I live in the South so I can keep wearing them till winter and even then I can wear them inside.  These sandals are also supposed to help with foot pain from heel spurs (which I have) and from plantar faciatis, which I do not have.  As far as shaping the legs, I'll just have to wear them longer to find out.
