Wearing high heels doesn't make women more attractive to men.

As time goes on, more and more women are realizing that High Heel Sandals can be tricky things to wear. If you are lucky enough to be tall and slim then you can look good in any style, but if you are short or have thick calves you need to choose more wisely.
Despite the fact that wearing heels changes a woman's posture and height in a way that presumably amps up their attractiveness, the men in the experiment couldn't tell the difference between a woman who was wearing heels and one who was not (unless the heels themselves were visible).

On a similar note, men are also pretty oblivious to a woman's choice in handbags. (And we didn't even need a study to pass along that tidbit of information.)
