1. Foot fetishes may be tied to the actual wiring of our brains. 

Neuroscientist Vilanayar Ramachandran, Director of the Center for Brain and Cognition at the University of California at San Diego, discovered a link between the brain and foot fetishes while working on research involving pain in phantom limbs. In trying to figure out how it is that amputated limbs can still cause patients pain, he discovered it had to do with the brain's own "body map". A body map is basically exactly what it sounds like, a guide that dictates which part of the brain control which part of the body.

2. A pantyhose (or tights) fetish is all about "perfection."

There's a reason that people who have foot and/or pantyhose fetishes are the most common of all kinksters. While the two fetishes are separate and distinct, there is some overlap, which makes sense if you think about it.

3. Foot fetishes might also be related to a fear of disease. 

Don't freak out. I'm not saying your passion for feet or for women in pantyhose is "sick." What I AM saying is that scientists have found a correlation between rising rates of sexually transmitted diseases in some populations and an increased number of people reporting to have a foot fetish.
