Not to stir up a pile of dust, but I received a pm from one of the Horween VP's ( guys last name was Horween) , when I posted in another thread about problems I was having with my #8's wingtips, where I can't seem to get rid of the very light scuffs despite my best attempts. And his recommendation was to use a bit of creme conditioner and the back of a spoon to rub it in, building up enough heat and friction to do the job.
I haven't tried it yet, so I can't comment as to its effectiveness. But it raises the question that many people seem to have varying beliefs on how to care for shell cordovan. Most of what I've read and seen tells us not to use a creme conditioner at all, just a very thin coat of wax. To paraphrase him, it would be an attempt to replicate the old deer bone trick for removing scuffs.
I plan to give it a try soon and report back. I'm wearing them now and hope to get more use out of them, but I can't stand to see the hundreds of small scuffs, simply from my heels kicking the rear quarters. The scuffs aren't deep or anything other than superficial, but they wont buff out regardless of the technique or pressure applied.
