I am unclear what number of shoes in rotation means within the context of your statement. I could have 101 pairs of Black Brogues, but by your statement they would all be useless if I bought just one pair of Burgundy Shell. In any case, it's not like shoes are terribly expensive, compared to suits. Also, this is supposed to be a thread about AEs, of which I have exactly one pair (Black Oxfords, natch), which come out for weddings and job interviews only. For everything else, there's Loakes.
