I absolutely love these! I received them as a surprise gift for Christmas. The heel is solid and sturdy. The photos here do NOT do the shoes justice, because the red detailing is a VERY vibrant, deep, and rich red. The zipper is strong and the fit is a dream. I will say that the bottoms of the soles are rather slick when they are brand new, so don't go flouncing around painted concrete floors or super smooth carpets until you've either walked on rough surfaces for a while or manually roughed the sole to get more grip. Other than that tiny detail, these are wonderful shoes! I normally take a wide, but these fit wonderfully in my usual size 9. I was dreadfully worried I'd have to ask my gift-giver for the shipping label to exchange them for a different size. Lucky me!
