When the Beastie Boys and other downtown New York style mavens wanted old styles like adidas Campuses and Puma Clydes, they went to old sporting goods stores or secondhand clothing stores and went digging. There were actually a few old shoes still being made in the early '90s — like Air Force 1s and Converse All Stars — but they had either never gone out of production or catered to a very small market. When Nike re-introduced the first three Air Jordans a few years later, they just sat there. And sat there. Most pairs were blown out for $20.
