I am going to assume they are true to size. I normally wear a size 5 because the smallest size is 5 1/2, so I got the size 5 1/2 and they were a tiny bit long at the toes. For the sale price right now, go for it, you won't be disappointed!
Very true to size. I wear a 5.5 and that is the size I purchased and they fit perfectly.
I wear 7 1/2 and they fit are very comfortable.
I wear a 7 and got a 7. The fit was excellent.
I wear a 7 and they were a true 7.
This sandal runs small, if you wear an 8, you might want to order an 8 1/2, good luck.
I am an exact size 8 medium. I just tried them on again and they do fit a little smaller than most sandals I have. I don't know if I would have gone up a size. Maybe if you have wider feet you should go up a size.
