For the gold or silver spot use a razor blade or knife edge on it. GENTLY scrape where the spot is, it will come off surprisingly easy. Any surface scuff that you make on the cordovan can be easily buffed out. I had a spot on a #8 NST that I used this trick and it worked great. BTW that's a great looking cigar Indy boot, wear them in health & congrats on your second little one. If it's a boy may I suggest Alden as a name.
