can develop a firm well shaped booty with the right choice of exercises, consistency, and other factors (i.e., good nutrition so said booty is not just made of muscle blurring blubber!). Sorry, no sneaker is gonna do that for you...What's a great booty look like as a result of proper training, nutrition, and consistency? Look up vids and pics of people such as well known fitness/figure model Monica Brant doing Straight leg deadlifts, and to paraphrase the classic line from the 80's movie Apex Booty Pop Crocodile Dundee, "That's not an a booty.. now THAT's an booty!" As a final comment regarding the Reebok commercial. If you are going sell a shoe that (supposedly...) shapes up your gluteus maximus, shouldn't you use a model that has one?! Holy Flat Backsides Batman! This gal has virtually no butt. Now I'm not hating on her; she's a very pretty girl - and for a typical TV model type - in great shape, but she has no a$$! I mean really, is that the behind most women really want today?
