Have you ever heard a sneakerhead say, "finally, my collection is complete!" I haven't either. The cop list can be anything you want it to be. Is there a sneaker you have to rock but don't have yet? Add it to your cop list and track it's activity. Can't afford buying a sneaker today? Add it to your cop list and buy it tomorrow. Your boyfriend won't stop wearing flip flops? Well, just go bid on any StockX sneaker ASAP and don't use the cop list.
