Nike + iPod Stand Alone Sensor

If your current sensor has been lost or exhausted its battery, get the Nike+ iPodŽ Stand Alone Sensor Kit. It's also a great choice if you want an extra sensor for a second pair of Nike+ shoes. Works with your Nike + iPodŽ Sport Kit to track your runs. Insert it into the built-in pocket beneath the insole of your Nike+ shoe and pair it with your existing Nike + iPodŽ receiver attached to your iPodŽ nano.
