I was very grateful that Mr Horween was willing to seek me out and offer his advice. I know cordovan can be tricky. I just think its interesting that there seems to be such varying advice. I do like the feel of them now that I've had them for nearly a year. In that time I've probably only worn them a total of 8 times.
I confess, I commited the worst of sins though. When I couldn't get the dark scuffs off, regardless of method or time spent, I took them to a cobbler who hit the rear quarters with essentially cordovan paint made for shoes. I told him I couldn't stand the scuffs, and he said that if he did apply the spray, it would be a bitch to clean and remove.
