I normally wear 6.5 in open toe shoes/ sandals and 7 in closed toe shoes. My feet are medium width. I purchased these in 7.5 after reading the reviews and I am really happy that I did! There was NO way that my feet would have fit in the 6.5 or even 7. They are beautiful shoes too! The leather is soft and I love the two tone of the nude and black. The entire sandal/ heel is matte and really stunning! I was looking at Stuart Weitzman Nudist but REFUSE to pay almost $400 for a pair of shoes! These, in my opinion, are even more stunning and have the same minimalist look, which was what I wanted. I am going to purchase other colors too! Highly recommend!
