"These are great shoes for an office environment. Classy and comfortable. I am a 6/6.5, and typically a 6.5 in SM flats. These were no exception. As with all my flats (every single pair, no matter the brand) I have to put a small bandaid on my heel when I wear them because they rub. With the bandaid they are great. I love that they are real leather and a true black color, not a greyish black that some shoes advertised as black are."
