the shoes are several years old and are sparing worn
Really? The evidence presented was, by its own account, the purported habits of a very limited segment of the population . . . 40 to 50 years ago? And one wonders whether their footwear of half a century ago matters any more than what the local burghurs in Kansas City wore in 1966. So the 80-90 year old set dictates style standards. Game, set, match to them! All that said, as others have already expressed, I am simply amazed at the shine on those PTBs of Macs. Excellent and beautiful.
Are you kidding me?? Uncle would be proud... excellent shine on your PTBs my friend! The only difference I see is maybe the picture quality and the lighting. Wear your PTBs in great health...
