I wear fitflop sandals as long as I can during the year. They are wonderful. I always hate it when the weather turns cold because nothing else is as comfortable as my fitflops. So when I saw these I thought at last something for winter. However, they are not the same as the sandal in comfort. My feet can last all day in the sandal without hurting. In these I can go about 4-5 hours. They look very nice on the foot and are warm. But the technology in the sole just isn't the same as the sandal. I got an 8 for an 8 1/2 foot.
