Guess what science finally proved: the appeal of high heels is that they accentuate feminine attractiveness.
In fairness to the actual study, the researchers acknowledge the high heels/attractiveness connection from the outset. Their study focuses on why high heels have endured over time. Their study found that heels do, in fact, give women a sexier walk. They concluded that this is a culturally influenced exploitation of our primal sexual urges.
Again, no shit.
Since women can be fired for being too attractive, I suppose women have a scientifically proven reason for ousting high heels as business attire.
