Glute Toning Trainers?

Long, long, story short, I need new trainers (tennis shoes, sneakers, whatever you may call them). While I seriously doubt a pair of shoes alone will make my bum tiny and perfect, I feel there isn't anything wrong with getting the right equipment to try, right? Here are the New Balance WW1100 Wellness Shoes. I love me some New Balance, and if these threaten to give my buns a better workout, I just might be suckered in.
