According to some research published in the Archives of Sexual Behavior (DOI 10.1007/s10508-014-0422-z; http://link.springer.com/article/10.1007%2Fs10508-014-0422-z#page-1)--summarized briefly in Psychology Today (April 2015)--a woman wearing high heels is perceived as more attractive than a women with low heels. In a series of studies by Nicolas Gueguen, it was found that:
(1) Men were more apt to help a woman if she was wearing high heels than low heels. For example, when a women dropped a glove, a man behind her was more likely to pick it up if she was wearing high heels. Sixty-two percent of men picked up the glove of the woman with no heels but 93 percent picked up the glove of the woman in 3 ½ inch heels. Heel height, however, made no difference in terms of another woman’s helping behavior.
(2) Men were also more likely to approach a woman if she was wearing high heels. With no heels, it took 13 ½ minutes for a man to approach her. But, with 3 ½ inch heels, it took only 7 ½ minutes.
The researcher postulates that one possible reason for these differences is the misattribution of sexiness and sexual intent.
