I remember someone asking about "pitting" with shell cordovan a few pages back, but I couldnt find the post to quote. Parts of my cambridges and patriots just wouldn't shine up with the mac method, so after about a dozen wears, I put a thin coat of allen edmonds cordovan cream on and viola! The pitting was significantly less pronounced and started to shine up like the rest of the shoe. It is still rougher than the other parts upon closer inspection though. Will plan on using the cream on my new strands after a few wears also.
