Sneaker Con bets NFC will keep fakes off its new shoe-selling app

Buying limited-edition sneakers, like Kanye West's Yeezys, isn't easy. Whether they drop on a site, in an app or a brick-and-mortar store, they often sell out in minutes, sometimes seconds. This sense of scarcity is what's behind the growth of secondhand online sellers such as StockX and GOAT, where you can find basically any hyped shoe that's ever been released by Adidas or Nike... for a premium, of course. What makes these sites popular is that they guarantee authenticity. With StockX, for instance, any pair you get from it comes with a QR code verification tag, but that's only for internal use. GOAT, meanwhile, sends you a letter saying the shoes have been authenticated.
