Two quick questions: 1) Do you guys treat the bottoms of your leather-soled shoes? Or will they be fine as they come. I've done this with Reno for my shoes once in a while but am not certain it provides much, if any, benefit. 2) Where does one acquire shoe sleeves (or bags?). You know, like the ones that AEs come with. I don't want the new suede shoes collecting dust on the rack and, apparently, Grenson doesn't supply any.
