The participants’ target choices by gender are shown in Table 1.
Table 1 Models selected by the participants
With all the measures, a Chi square goodness-of-fit test was performed in order to assess whether there was a significant difference or not between the three possible choices offered to the participants. The results of the tests conducted with both male and female participants showed a highly significant effect on all the dimensions measured. A greater number of participants selected the target with high heels as the sexier, the prettier, and the more elegant, with the more attractive legs and buttocks. The same target was also perceived as the younger person and the photograph that would be preferred by others and the more appropriate for a photo album.
All the results reported were observed with both male and female participants, and the results of a statistical analysis examining the effect of participant gender on the choices of the targets showed participant gender to be non-significant. This non gender effect in the evaluation was congruent with the findings found by Morris et al. (2013) who presented women walking in flat shoes and high heels with the help of point-light videos of the women walking. The authors reported that both male and female participants evaluated the gait of the targets in the high-heel condition as significantly more attractive than the women in the flat-heel condition.
Our findings clearly show that the profile of the woman target photographed when she was wearing high heels was selected as the more attractive physically by both male and female participants. Significantly, the participants were not conscious of the difference between the two photographs used in this experiment.
Such results are in line with the findings reported by Guéguen (2015) and Guéguen and Stefan (2015) who observed in several studies that men approached a woman wearing high heels more readily. Our results were also congruent with the findings of Morris et al. (2013) who reported that women wearing high heels were perceived as more feminine. However, in these studies, most of the women targets were walking, and research has shown that the nonverbal behavior of women, including gait, was associated with variations in men’s judgments of attractiveness and behavior (Guéguen 2010; Moore 1985; Moore & Butler 1989; Walsh & Hewitt 1985). It has also been found that the attractiveness of gait varied with the target’s age (Montepare & Zebrowitz-McActur 1988), with younger walkers rated higher in sexiness and happiness. High heels could have influenced the women’s gait or posture, which in turn influenced their attractiveness to men. However, the present study findings regarding a static target show that a change in the gait is clearly not the only factor that could explain why women are perceived as more attractive when wearing high heels. Fessler et al. (2005) reported that the small foot size of female targets increased their attractiveness to men, but in our study, the target’s feet were not visible. Men’s preference for women with morphological traits associated with youthfulness (Buss 1994; Symons 1995) is confirmed in our study, as the target with high heels was perceived as younger than the target with no heels, which suggests that heels could increase the perceived youthfulness of women.
Thus, overall, these new findings expand those reported by Morris et al. (2013), Guéguen (2015), and Guéguen & Stefan (2015). We also found that the legs and the buttocks of the woman were perceived more positively when she was wearing high heels. It thus seems that the appearance of the body profile, and not only the gait, becomes more attractive when a woman wears high heels. This positive effect on body judgment was also found with the female participants.
Smith (1999) and Smith and Helms (1999) stated that high heels act as secondary sexual characteristics that could increase the attractiveness of women to men. Even if high heels do increase the femininity of the gait, our findings show that other aspects of body appearance are also affected by shoe heels, even when the heels are not seen. After analyzing the cover photographs of pornographic magazines, Dietz and Evans (1982) reported that over 50 % of the female models wore high heels. Thus, men could falsely attribute sexual intent to women wearing high heels. Since in our study the target’s shoe heels were not visible, this connotation or misattribution of sexual intent cannot account for our findings.
While Morris et al. (2013) showed that the gait of women wearing high heels is perceived to be more feminine, our findings suggest that high heels also increase the attractiveness of women’s morphological and body traits. Previous studies examining posture and judgments of attractiveness have reported that postural appearance influenced judgment. Gitter et al. (1982) instructed participants to examine drawings of male physiques manipulating five somatic and postural dimensions of appearance (abdomen, shoulder, neck, head, and body shape). They reported that the abdomen factor was responsible for the largest percentage of the variance; a protruding abdomen was associated with negative ratings, whereas its absence was associated with the most positive ratings. Osborn (1996) also examined color photographs of Caucasian women with slumped, normal, or military attention-style standing posture. This author observed that the slumped target was perceived to have more medical problems, to be less fertile, less likely to have an extramarital affair, and less attractive physically. In this study as in our own study, the target was static, which could suggest that wearing heels is associated with changes in women’s posture that are perceived more positively in a large range of dimensions.
Hence, the impact of heels appears to be twofold: first, heels change the gait of a woman, hence change judgments of her attractiveness when she walks; second, heels also change her posture and body when she remains static. This could explain why men approach women with high heels more readily, and why women wear high heels even if back or foot damage is associated with walking in high-heeled shoes (Cronin et al. 2012; Saltzman 1998; Smith 1999). Wearing high heels could be an element of mate selection for women who thus increase their attractiveness to men and decrease the competition with other women.
