This is my third pair of FitFlop sandals and I love these just as much as the others.  I find these to fit true to size!  I have walked many miles in my FitFlop sandals and never had any problems.  I have a high instep (and bunions) and was concerned that the straps on this style would be too tight.  Luckily they fit perfectly and are very comfortable.  The soles are just like the other FitFlop Flip Flops, so they give a lot of support and comfort.  I am looking forward to wearing these on my vacation to the Bahamas...lots of walking to be done!  I highly recommend these sandals.
