The shoes that I was referring to are calf leather. They do seem to be benefit from brushing rather than regular polishing. It strikes me that shoe product makers certainly have a vested interest in promoting the idea that we should spend most of our lives polishing shoes. I have lots of jars and tins of creams, waxes and conditioners, as I imagine many people on this thread have. I'm finding, though, that the most useful products are my horsehair shoe brushes.
