Definition: Foot fetishism, foot partialism, foot worship, or podophilia is a pronounced sexual interest in feet. For a foot fetishist, points of attraction include the shape and size of the foot and toes (e.g., long toes, short toes, polished toenails, high arches, soles etc.), jewelry (toe rings, ankle bracelets, etc.), treatments (such as pedicures or massaging), state of dress (barefoot, flip flops, etc.), odor, and/or sensory interaction (e.g., smelling the foot, licking, kissing, tickling, etc.)
Neuroscientist V.S. Ramachandran said in Phantoms in the Brain: Probing the Mysteries of the Human Mind:
Maybe even many of us so-called normal people have a bit of cross-wiring, which would explain why we like to have our toes sucked.
In his theory, Ramachandran claims that the part of the brain that corresponds to the genitalia and feet are adjacent to each other in the brain’s body image map which results in cross-wiring in the brain between the foot and the genital parts, and therefore the sexual interest in feet.
Many sites took this statement as their reference to accounnce the cause of foot fetish such as livescience.com.
Is there is some scientific evidence that shows that this specific cross-wiring in the brain may or will cause foot fetish? How does Ramachandran's scientific theory stand in the medical domain? And is it scientifically verified that genitalia and feet nerves are cross-wired in the brain?
