LOL,

you expect a peer reviewed scientific journal to have research on high heels?
Social scientists study all kinds of weird stuff. High heels? Open toed shoes? Falsies? They're all fair game in the weird world of the social sciences.High heels aid in attracting a good mate.
E.O. Smith (1999). High Heels and evolution: natural selection, sexual selection, and high heels.
Psychology, Evolution, and Gender, 1 (3), 245-277.
While it is unlikely that there is a gene for wearing high heels, the tendency to wear high heels under certain social conditions may be a manifestation of a larger pattern of behavior associated with mate attraction.
High heels help women get help from men.
M.B.Harris and G.Bails (1973). Altruism and sex roles.
Psychological Reports, 32, 1002.
It appears that the likelihood of an altruistic response is indeed affected by sex-role stereotypes. Women wearing feminine attire [ruffled blouse, high heels, and curly hair] are more likely to be helped, particularly if they make a feminine request for help ["My shopping cart is stuck. Can you help me?"]

N.Guéguen (2007). Bust size and hitchhiking: a field study.
Perceptual and Motor Skills, 105 (3), 1294-1298.
To test the effect of a woman's bust size on the rate of help offered, 1200 male and female French motorists were tested in a hitchhiking situation. A 20-yr.-old female confederate wore a bra which permitted variation in the size of cup to vary her breast size. She stood by the side of a road frequented by hitchhikers and held out her thumb to catch a ride. Increasing the bra-size of the female-hitchhiker was significantly associated with an increase in number of male drivers, but not female drivers, who stopped to offer a ride.
Or maybe women wear high heels because foot fetishes are safe sex?

A.J.Giannini et al. (1998). Sexualization of the female foot as a response to sexually transmitted epidemics: a preliminary study.
Psychological Reports, 83 (2), 491-498.
The authors reviewed historical literature and hypothesized a relationship between epidemics of sexually transmitted diseases and foot fetishism. They tested this hypothesis by quantifying foot-fetish depictions in the mass-circulation pornographic literature during a 30-yr. interval. An exponential increase was noted during the period of the current AIDS epidemic. The authors offer reasons for this possible relationship.
