These are J.M. Weston 598s. They are black Russian calf. The size is 6 / (6.5) C width. Markings inside the shoes: 312419-4 25-301-598-21 6/ C I previously purchased these used, but I am selling them because the size doesn't fit. The heel lining has been repaired. There are some wrinkles and scuffs, but the leather condition seems to be good. These are used items, so please understand this before purchasing.
