I have been wearing FitFlops for years and love them. The ones with the straps in the back help to keep them on, which is good if I plan to be walking any distance, to avoid fatigue in my feet. Im in Fit Flops about 6-8 months a year and they offer me great arch support for my flat feet. I found this style to be true to size. I wear an 8 1/2 shoe and order an 8 FitFlop. Some other styles run large and have had to order a 7. They only come in whole sizes. so the 8 fit perfect. I did not find them to be too narrow, or wide.
