Using Nike sport iPod Nano accessory with any trainers

I was looking into getting this accessory for an iPod nano that wirelessly transmits from your running shoe to your iPod nano which is small enough to bring on runs with you.

Apple Store Nike + iPod Sport Kit

I like the idea of being able to track my running progress with a Nano. I was not impressed with having to switch to Nike running shoes from my Asics to use it. There is a notch that's cut into Nike's new shoes for the transmitter to fit into. Since the Sport Kit transmitter is just an accelerometer there is an easy way to attach it to shoe laces instead.

I have seen some home made Velcro versions of sticking the transmitter into your laces but I wouldn't fancy its chances of staying in there during a long run when marathon training. After a bit of searching there is a product to do this called Shoe Pouch
