BOOTS complexion?

I asked BOOTS why he doesn't wear shoes since he shines them. He said it 'ruins' hes complexion.. Whats that suppose to mean? So I looked it up and this is what it said; Complexion refers to the natural color, texture, and appearance of the skin, especially that of the face. I guess I know BOOTS is talking about.. he would look weird if he had shoes now that I think about it.
