I should have paid attention to the reviews. I was desperate, needed to buy black flats. I bought a 1/2 size up and yet, these continue to rub my right heel. I figured as they are leather, they will stretch. Hasn't happened yet. The styling is cute, but I'm sure I could have found more comfortable flats for less than what I paid for these. Also rubbing on the outer bones of my feet. There's something amiss with the structure of these shoes. Seriously considering returning these....
