Hello everyone, i hope someone can help me out here. Recently got a pair of 97s. I wore them only four times. While cleaning them I noticed a huge scuff on the heel. When I got something similar on my 95s and other pairs I was able to remove them with either toothpaste, vinegar or nail polish remover. I tried al these here but with no success, it didn't make the scuff even at least less visible. Any recommendations what I should try?
