The “Dancepants” convert kinetic energy from your rapid movement into electricity to run your MP3 player.  In layman’s terms: you run and the music plays; you stop running and the music stops playing.  The designers say the leggings are a “100 percent interactive way to feel the value of energy on your own.”

Pretty neat way to keep you going at a fast pace when exercising or making a quick dash to your next class.  If you want your beats to keep playing you gotta shake your groove thang, shake your groove thang.
