Answer: Yes, always water-proof, it will do no harm. If you want both shiny, you can either apply a shiny finish (my choice would be Angelus), or a good conditioning can bring a nice sheen as well (this will not last more than a few days though generally). If you want both dull, take a cotton ball or q-tip, dip it in nail polish remover and VERY LIGHTLY go over the whole upper of the shoe that is shiny, as this will remove the factory finish.
