Nike’s latest Facebook App is a fun tool for sneakerheads and newbies alike to customize, trade and share sneakers virtually, online. Using the Nike Shoe Boxxx App, users start with three pairs of shoes and, through trades, Facebook shares and “Likes,” and other online moves, start building their ideal online footwear collection. It’s a great way for people to get educated on sneakers, or – for the real sneakerheads out there – to get your virtual fix online. Check it out here.
