These shoes are really very cute but they are unbelievably narrow. My wife has very small feet so the 5 U shoes will fit them. This time I brought the shoes in 5.5 U(M), but they are crazy narrow and 2cm longer for her feet. When you look at the inside, you will find the very thick shoe-pads, so there is no enough room for foot. Because they are sent to China directly, so I don't intend to retune. Only buy these if you have a narrow foot.
