Whats the difference between all the reebok toning shoes?

Kayley asked:


I know that there is reebok easytone, runtone, and simplytone. easytone is for walking, runtone is for running, what is simplytone for? And does it still work if you run in easytone or walk in runtone? Also since simplytone is cheaper does it not work as good?
