I keep a shine kit in the kitchen, and give my proper shoes a good going over, after they get mucked up a bit. Spray them down with foot powder, and a quick dab of polish.. If I have something going on, I am usually going over my outfit the night before, checking for any mending, spit polishing the shoes, and pressing, I being raised military and serving... old habits are hard to break.

As for the shoes, I am actually looking for wingtips/brogues for myself. I am currently wearing a more informal shoe at the moment, but it works for my informal wear.
