Shoes that can tone your bum?

So I fell victim to great marketing once again... or did I? My mom has been in town these past few days (which has been wonderful!) and she took me shopping for my birthday present. One of the things I have wanted are the Reebok Easy tone shoes. So here is what I got:

I plan on wearing these every time I walk my dog, walk on the treadmill and go to the gym for the next 30 days and I will report back and let you know if my bum looks like this by March 1st:

A girl can hope right?!!?

Also they now make ones for running, the salesman at Dicks' informed me that they DON'T work while walking though, only when running...WTF? Doesn't that sound ridiculous!!! The sole on these look different here is a picture

Well wish me (and my bum) luck and I promise to let you all know how it goes!
