I had tried these on in a shoe store so I knew what I was getting in terms of fit and they fit perfectly and felt terrific.  In fact, I immediately went online to see if the price was better (it was $12 cheaper through Amazon) and ordered them up.  They're a terrific flipflop.  I wore them to work on casual work day for the entire day into the evening on my first time wearing them and have not one complaint.  I'm a flipflop wearer so the lack of arch support and a rubber sole doesn't bother me in the least.  The fabric is what sold me as the top fabric surrounding you foot and heel is very soft and pliable and stretches to fit your foot perfectly.  I wish I had several pairs in various colors!!!
