I have 3 pair of my own fitflops and thought my husband would find them as comfortable as I do.  Turns out he does.  the fitflops are well made and are very light.  They're easy to walk in and you can spend a lot of time on your feet and not feel it in your legs or back.  I highly recommend fitflops to anyone looking for a comfortable shoe or sandal.  To me the fact that they are supposed to help tone your legs is a side benefit.
