Hey, didn't some other brand just do the "your ass will look better if you wear our shoes" thing? Now Reebok's doing it. Or was it Reebok in the first place? We're too busy at a conference having fun to take the time to find out. And besides, why analyze an ad when it needs no analysis? A hot ass attracts eyeballs. And in advertising, that's half the battle. And it might even sell some shoes.
Now go buy some Reebok's so we can claim we know what we're talking about as opposed to appearing to be some sort of ad hack with nothing better to do than leer at women's buttocks like a Neanderthal who's been away from his woman on a long hunting trip.
