That is too cool! I have been thinking how amazing it would be if I could get the HRM info and/or workout synopsis from cardio machines logged into my iPod somehow. With something like this available, that might not be too far behind.
I read about this in the paper this morning. It will be available in the UK in a couple of months so it should be out in the US even sooner. The sensor that you put into your shoe will costs about £30 and the special shoes themselves will start at about £60.
Its such a fab idea. Nancy, Im sure HR info wont be far behind!
