mephisto womens shoes size 8 loafer

These shoes are in good preowned condition. They do have signs of wear but plenty of life left in them. I am not sure what the white powder is on the bottom of the one shoe almost like they stepped in something and it left it into the impression. I know it looks odd, but it's nothing. These shoes are soft as better. I don't see any damage or any flaws other than the residue in the bottom of the one shoe I'm always available to answer any questions thank you so much for looking.
