The Shoe Pouch was designed to allow runners and walkers to use the Nike+iPod Sport Kit® (NOTE: the Nike+iPod Sport Kit® is sold separately) with regular running shoes. Made from strong, stretchy neoprene, the Shoe Pouch safely stores your Nike sensor on top of your shoes. Attached via your shoe laces, the Shoe Pouch allows the Nike Sensor to accurately transmit your running data to ensure you have a hassle-free run.
