These sandals are super comfortable! I would recommend them to everyone, but there is one drawback for a lot of people...there is no adjustment on these shoes. There is a bit of elastic where the strap attaches to the sole at the instep, but other that that, no adjustment. Luckily, I am almost a perfect size 11 and they fit me wonderfully. I don't have to keep pulling the strap up. I would say that if you are in doubt, you should order half a size smaller. The insole is pillow soft and if you get the correct fit, these sandals will never leave your feet.
