I'm highly skeptical of this particular study, since, as *not* reported in this particular incarnation of the news, the lead researcher is an admitted fan of women in high heels.

For example, this site:
http://mhtoday.menshealth.com/

contains the excerpt: "She loves wearing high heels and got tired of hearing about their supposed health drawbacks"
