The fact that these guys keep straight faces playing shoes is impressive.

Somewhere in a top secret location in Tokyo, break beat music duo, HIFANA (composed of KEIZOmachine and JUICY) discovered that Nike Free Run+ running shoes can drop beats like realtime samplers and no other. HIFANA eschewed a part of their regular break beat set up and hooked up the mixers and sound systems to Nike Free Run+ shoes. When bent or twisted, the ultra-flexible Nike Free Run+ drops different tunes and sounds.  Via Freshness Mag
