Q: do i need a nike  shoe sensor with 7th gen ipod nano

Hey faye88,

To use the Nike + iPod system with your nano, these are the requirements:

1. What do I need to get started using the Nike + iPod system?
   You need:
   • An iPod nano, iPod touch (2nd generation) and later, or iPhone 3GS and later
   • The Nike + iPod Sport Kit  if using an iPod nano or the Nike + iPod Sensor if using an iPod touch or iPhone
   • Nike+ ready shoes
   • iTunes 8 or later
   The Nike + iPod Sport Kit is designed for running and walking. Nike+ ready shoes are highly recommended, as they have a specially engineered pocket in the midsole of the shoe for the Nike + iPod Sensor. The Nike + iPod system works with any iPod nano running the latest software, iPod touch (2nd generation) and later, or iPhone 3GS and later.
