We already know heels ramp up your fashion appeal, but science says they make you sexier, too. According to a study in the journal Archives of Sexual Behavior and published in Time, high heels increase a woman’s attractiveness. In three separate experiments, Nicolas Guéguen from the department of social behavior at the University of Bretagne dressed French women in the same black suits with a straight skirt and white shirt. The only difference was their shoes. The study found men were more receptive to women, and willing to help them, in high heels as opposed to flats. When one woman dropped her glove in the experiment, “95% of men chased after the women when they wore high heels to return the glove, compared to 62% of those who did when she wore flat shoes.”
