Old shoes doesn't sound interesting but I managed to find some fine examples, from the incredibly short and tall Venetian Chopines which had 2 foot soles for courtesans to wade through sewage lined streets to the opposite shaped long skinny medieval Poulaines which had toes stuffed with moss. Interestingly the worlds oldest shoes come from the New World, or Oregon to be exact.My personal favorite are the Roman shoes from the time of Constantine, whose style show just show eastern or to our eyes, Arabic, the Empire would have felt at that time.
