I believe I've heard that a spit shine is where the finish on the shining gives the shoe a "shiny" mirror-like appearance. Is this correct? If so, my question is how well does it work? I have a pair of Johnston and Murphy Cellini oxfords that I really love. The leather, I think, is pretty darn good. The only problem is that it doesn't have the shine that cordavons do. I'd like to give it a little bit more of a high shine and don't know how. Should I just go to a shoe shine guy in the subways or get my own kit?
