I had to return these for a larger size. It seems like I am not the norm though! I wear 6.5 in all other shoes and these were almost perfect. I found that the backs rubbed really badly. I did not have a problem getting my feet into these shoes at all! I wasn't able to wear these comfortably with socks. So I'll size up just a .5 size and see if they are better. Other than the size, these are very comfortable. Not tennis shoe comfortable, but definitely better than your standard flats. I would say that these are probably not going to be your tour the city shoes, but definitely comfortable for flying and light walking. I love the art work and they are so cute!
