I usually wear an 8 or 8 1/2 and got a 9 after reading reviews and they fit perfectly. The space for toes is a tad narrow but is fine. The straps fit me just right on the last hole, so particularly thick ankles may not fit. They feel fun to wear, I feel like a ballerina! I also like that the sides come up a bit farther than some of my other flats-- I wore them in the rain without getting worrying about tiny splashes getting my feet wet. I got the tan which actually looks more like the one labelled "Tan Ts," darker and more brown, which isn't exactly what I wanted but I love them so much I decided I'll keep them and just get a lighter color later!
