I know that is a crazy thing to say. I was hoping it might grab your attention. The reality is someone in the world of six billion people may actually want to buy your old sneakers. My ebay account is filled with sales of crazy stuff I used to own. I once sold a pair of jeans that had a ink spill on them. Turned out some movie director liked my jeans and needed them right away. Go figure! Who knows why someone would want to buy your old sneakers? But really, do you care? If they want to hand over the cash, I say go for it!
