I bought this for my wife who really wanted new Rainbows (a brand she used to love and rave about endlessly). She has incredibly tiny, thin, feet and while the sandals are the perfect size, the straps are way too tight and she can barely slide her feet in. After a week of trying to break them in, she went back to wearing her plastic Havaianas. Feels a bit like a waste of money but I'm still hoping they will eventually get wider and fit properly. I guess we should have paid a bit more money for Rainbows we have tried before.
