I bought the shoes from the Sante website. I wore them four times. Their interior made my foot completely black. I sent an email to the company, but no one ever responded. I called and the answer I was given is that the leather fades like that. Obviously, if it was real leather, it wouldn't fade... and they told me that maybe it's my foot's fault. Well, that's convenient. A friend of mine who bought them had the same problem, maybe it was her foot's fault too. Otherwise, very elegant and comfortable.
