Shoe Pouch for Nike+ iPod Sport Kit, and Nike+ SportBand (2-Pack), Also Fits Adidas miCoach Speed Cell and Garmin Foot Pod
I have used both the original shoe pouch and this new version and I love them both. Your iPod transmitter isn't going to come out of this and moving the transmitter from one shoe pouch to another is easy (if you happen to have multiple pairs of shoes as I do). You get some protection from moisture by having the transmitter encolsed. If you have an iPod but dont use Nike shoes this the way to go.
