Nike Air Zoom Plus Running Shoes - The Nike Air Zoom Plus Running Shoes was the first style to be Nike+ enabled. Under the left insole you will find the 'port' for the Nike Sport Pack transmitter. The shoe itself delivers a responsive ride with excellent midsole cushioning. The Nike Air Zoom cushion pad at the Rear Foot provides good protection and the flexibility of this model will ensure a smooth transfer from heel strike to toe off.
