Adidas is known for making connected shoes -- but never quite as linked-up as a Nash Money concept making its appearance late into the London Olympics. The Social Media Barricade weaves the guts of a phone and a basic two-line LCD into a running shoe, letting the footwear take Twitter updates very literally on the run through a public account. Even the signature Adidas stripes change their hue through remote control. Before anyone gets visions of athletes checking congratulatory tweets after the 100-meter sprint, just remember that it's an idea rather than a production blueprint: although Adidas is quick to call the Social Media Barricade the "future of athlete connectivity," the only athletes putting eyes on a pair right now are those swinging by the Olympics' media lounge for interviews. Knowing this, we can still imagine some future shoes padding runners' egos at the finish line during the 2016 Rio games.
