"I am usually a solid 7.5, but I will fit into 7's and 8's depending on the shoe. After reading reviews of others in my size range i opted for the 8's in these sandals. They fit well, the elastic straps are not taught on my calf, even though I would say I have moderately full calfs. This leaves the elastic a little wrinkly, which I'm hoping will smooth out with some wear. Otherwise very comfortable and cute!"
