According to a French study published in the journal Archives of Sexual Behavior, men are much more willing to approach and help a woman wearing heels than any other type of shoe.
The study had a woman approach strangers and ask them to complete a survey, once in flats and the second time in heels. Guess when men were more willing to complete the survey? Yep, when she was wearing heels.
Researchers then asked the woman to drop her glove in a public place in heels and out of heels. Guys helped her out more when she was in heels. Lastly, they had a woman go into a bar, and, you guessed it, she was approached by men much more frequently when wearing heels. (You Beauty)
