Practically everyone raves about these flipflops but I was not quite as impressed. Overall they are comfortable,but  the bottom of my feet sweat in them; and that is just around the house in the winter. And my feet rarely ever sweat. I am a Yellow Box junkie and got these for a 'different' look. Will probably keep cause they are nice looking and it is too much effort to return. As for size, I usually wear a 6.5 in flops and 7 in enclosed shoes. Got these in 6 and they are perfect. Oh, they ARE adjustable, but the Velcro is very well hidden, almost impossible to see.
