First there was the iPod Sock....now meet the Athletic Sock. The new-fangled Athletic Sock meets all your high-tech running needs and allows you to use your favorite, stylin' pair of running shoes at the same time. The Nike+ does not require pressure for an accurate reading. It measures accurately while securely mounted on the front of your laces.
Another bonus: this is an ultra-quick knit project that will use up some of that yarn scrap you can't bear to toss.
