Would one only collect shoes in their own size? Or is it irrelevant?
If you plan on resale, probably best to get them in the more popular sizes. @matt100's collection is worth a pretty penny mind you. When he does decide to sell assuming he got them at retail prices he is going to be like Scrooge Mcduck. The two pairs I'm really jealous over combined are probably best part of 2.5k and that's only the ones I can see!
