I have a pair of recently re-soled black calfskin wingtips. I'm not real big on full brogue style shoes, in general. In any case, I have an option to buy a pair of black Shell Cordovan wingtips for a relatively moderate price, which, if they were brown, I would have already ordered and would be in transit to me. My question is - other than being more durable, is there any advantage to black shell cordovan? I do already have a pair of black shell cordovan in another style, but have not had them for long. Does the Black cordovan develop any patina alike the Brown does, with age?
