Today I want to take a serious look at the science of foot fetishism: what neuroscience and psychology can tell us about the mind behind a foot fetish.
Foot fetishism is the heavyweight champion of fetish psychology. In every survey about fetishism, it always ranks first. A 2006 study from the University of Bologna in Italy found that among people with a special interest in certain body parts, 47%—almost half—were attracted to the feet or toes of the opposite sex. In 2017, a Belgian study found that 17% of the men interviewed at random said they considered themselves to have a foot fetish.
Isn’t that strange? Aren’t they just a pair of smelly feet? They’re not exactly body parts directly involved in reproduction or procreation. So how can they be so sexy?
Let’s start with a relatively old explanation.
Otto Fenichel, a psychoanalyst and disciple of Freud, once proposed that foot fetishism has a close relationship with castration anxiety.
Castration anxiety is one of Freud’s spectacularly ridiculous theories. He said that when boys first discover that girls don’t have penises, they assume the girls have been castrated. They then fall into deep fear, worrying that one day their own penis might get snipped off too.
Fenichel, the psychoanalyst, said that to cope with this fear of the female body—especially the fear of losing their penis—some men might shift their attention to women’s legs or feet. That way, they could obtain sexual satisfaction without directly confronting the body parts that frightened them. If the fear was especially strong, they might even avoid women themselves entirely and become interested only in women’s shoes.
That’s the logic behind deriving foot fetishism from castration anxiety. Pretty ridiculous, right? In Freud’s world, everything men fear comes from being afraid of losing their penises, while everything women worry about comes from the fear that they never had a penis in the first place. Whatever he said, he could make it sound right—and there was no way to test any of it anyway.
A somewhat more plausible guess was proposed by neuroscience heavyweight V. S. Ramachandran, author of Phantoms in the Brain and The Tell-Tale Brain. He found that in the human brain, the regions representing tactile sensations from the feet and the genitals are actually right next to each other.
More specifically, this area is called the somatosensory cortex. Every part of the body—your face, lips, armpits…—has its own patch of neurons there, responsible for producing tactile sensations from that part. In this area, the neurons responsible for tactile sensations in the genitals happen to be neighbors of the neurons responsible for sensations in the feet. That means activity in the two regions might interfere with each other. Stimulate the feet, and the genitals feel something. The reverse can happen too.
Nearby electrical signals interfering with each other isn’t unusual in the brain. The technical term is neural crosstalk.
This finding can explain rather beautifully why foot massages feel so good to some people: “The pressure is here, but the pleasure is somewhere else.”
Some people also think this explains foot fetishism, since sensations in the feet are connected with sexual pleasure.
But I think there’s still a missing link here. What gets me turned on is obviously my own feet. So why don’t we fall in love with our own little feet? By this logic, Quentin Tarantino—the world’s most famous foot fetishist—shouldn’t insist on giving the actresses in every one of his films all those close-ups of their feet. He should get in front of the camera himself. He ought to give his own feet plenty of close-ups and invite the audience to admire “a big guy picking his toes” along with him.
But foot fetishists are clearly attracted to the feet of the opposite sex. Why? I dug through the literature from top to bottom for ages, and discovered that this is a theoretical blank spot. My guess, though, is that mirror neurons are probably involved. Mirror neurons are the brain’s automatic replay machine. Their job is to reproduce other people’s movements. Whenever we notice someone performing an action, our mirror neurons activate the corresponding motor cortex in our own body, making us automatically imitate the action in our minds; sometimes they even make our muscles actually move along with the other person, just a little. Many scientists believe this is the source of all human learning, imitation, and empathy.
If we take mirror neurons into account, then when we’re watching an attractive member of the opposite sex, all their movements will make our own muscles twitch slightly as we imitate them. The strange thing is that whenever we unconsciously and subtly imitate the movements of their feet, the friction and pressure on our own feet may, through the neural crosstalk I mentioned earlier, trigger a certain degree of sexual pleasure. And so the connection between the feet of the opposite sex and sexiness gets established in the brain.
That’s the most self-consistent neural mechanism I can come up with for the psychology of foot fetishism.
But this still can’t explain one crucial phenomenon: why the gender ratio among people with foot fetishes is so wildly imbalanced. Remember that Belgian study I mentioned at the beginning? It found that 17% of men said they had a foot fetish. But in that very same study, only 4% of women said they had a tendency toward foot fetishism. The gender ratio is wildly lopsided. That also fits our impression, doesn’t it? The people who say they have a foot fetish are basically all men.
So why is that? I honestly couldn’t find any relevant research on this either. But intuitively, I think it has something to do with the aesthetic value of men’s and women’s feet themselves. I suspect that even if an alien came here and looked at them objectively, the curves of women’s feet would simply be more beautiful. The feet of a big guy picking his toes would probably be rejected even by an alien. But when it comes to this purely artistic kind of aesthetic judgment, I’m really out of my depth, so I won’t go into it. Everyone is welcome to share their own opinions and add to the discussion in the danmu and comments.
