Men's Slip-On medium gray leather shoes by PRADA. Made in Italy in the 1970's. The shoes feature hard rubber heels and soles. They are marked size 11 1/2. The outside of the shoes measure 13.25" long x 4" wide. They are leather lined. They are in excellent pre-worn condition. They have a few light black marks on the inside of outer shoe which is light and no one can view. The left shoe is lighter in color. The front of that shoe looks lighter; someone might have spilled some liquid on the shoe. A quality craftsman shoe repair person can darken the gray. How often do you find a great pair of Prada shoes from the 1970?
