I love these shoes. My feet are very narrow and also thin (heightwise) and I have always flip-flopped and clenched my toes to keep my feet inside my old fit-flops. These fit my freakishly narrow feet! I even had to adjust them to the second hole, not the first. Am so pleased. The only con in my opinion is the firmness of the piece between the toes. It takes a little while to get used to. No blisters, just a little soreness that goes away after a few days as your feet become accustomed to these shoes.
