According to Engadget, Nike President and CEO Mark Parker has unofficially announced (via an interview) that all future Nike running shoes will be compatible with the Nike + iPod Sport Kit by 2008. For those of you who aren't familiar with the setup, that basically means that one shoe of every pair will have an aptly sized notch cut out in order to accommodate the wireless transmitter that comes with the Sport Kit. This hardly solves the problem for joggers who prefer not to run in Nike shoes, but this simple and inexpensive hack sure does.
