These shoes were purchased by me over 35 years ago. I have not worn them in at least 25 years, lol. I am not even going to attempt to clean the bottom, I wouldn't know what to do. These are size 8.5 B and in very good condition otherwise. These re 35 years old, they are not perfect but the shoe is sound, the material and tag are in excellent condition and aside from the bottom, there is relatively little visible wear.
