When I first received these boots I was very disappointed.  I had just spent 5 months wearing FitFlops sandals and I had looked forward to their boots and shoes.  Well.  The boot is SO wide!  I really thought that I'd have to send the boots back.  I decided to use a Dr. Scholls gel insert to tighten them up.  OH HAPPY DAY!  It totally worked and I now am walking around in my beloved FitFlops again, just in boots now instead of sandals.  I bought a different model boot from FitFlops, same width problem, and tightened then up with Dr. Scholls gel insert as well.  Same deal with a pair of their shoes.  I'm so happy I can continue to wear this brand during all the colds months.  I love FitFlops!!!
BTW:  If the boots hadn't been so wide and I had to pay for an insert to tighten them up, this boot would have gotten my HIGH FIVE!!!!
