Grantwood Technology has announced its Shoe Pouch that holds the sensor for Apple's Nike+iPod Sport Kit for the iPod nano. The case mounts securely through the runner's shoelaces, allowing the Sport Kit sensor to be used with most footwear beyond the intended Nike+ shoes, says Grantwood. The pouch also serves alternate uses such as holding the transmitter itself after exercise or a set of small keys, says the company. The Shoe Pouch will ship on November 1st for $6.
