We're generally quite wary of any video meant to "go viral" and "sell a lot of shoes" (or sell a lot of whatever), but from time to time something comes along and cracks our jaded shell. Case in point: the new Japanese campaign for Nike's Free Run+ running shoes sees experimental musician / DJ Daito Manabe and co. bangin' out a tune with the company's newest. The kicks are outfitted with flex sensors (which change resistance when bent), allowing some impressive control of effects via Max/MSP and Ableton Max for Live. Have you ever wanted to hear a hip-hop version of Thus Spoke Zarathustra? How about one performed on running shoes? You're in luck -- we got it for you after the break.
