iPod is making the nano even easier to run with. In the next month or so they are supposed to begin selling the Nike+iPod Receiver Kit. A sensor that you can put into the insole of a special pair of Nike running shoes and a companion wireless receiver that clicks into the dock of the nano (not using the earphone input). The iPod will then track your pace and distance as well as play your own specified pep up song when you start to flag. It will update your workouts on your computer when you sync up and they even mention something about being able to compare with your friends. Soon after Nike will start selling their special shoes with a pocket under the insole. Assuming the user interface is easy to use, this could possibly be an amazing training tool.

But my question is how does this sensor work? Would it be possible to clip it to the outside of a non-Nike shoe and still get decent stats? Because most runners are very picky about their footwear and if they don't like Nikes then I don't see them switching over just to get the extra iPod perks. I wouldn't, I like my Brooks. I could see less picky runners going in for it though. The $29 price tag doesn't seem that bad though.
