I just purchased these shoes in the Olive canvas in a 7, which is the size that I wear for most ballerina flats. However, THEY WERE TOO SMALL!!! On the website it suggests ordering a 1/2 size smaller, but I would suggest a 1/2 size smaller than the largest size that you wear! I on average wear an 8 in most sneakers and a 7.5 in heels and a 7 in flip flops or flats. I could jam my foot into the 7's and thought that with some stretching they would get better but eventually faced the fact that with my toe pressed against the fabric in the front, I would very soon have a hole there. I am giving this pair away and just ordered another pair a half size larger. :-) Hope this helped in deciding what size to get, because I know I was very confused when I purchased!
