No, but the closeness in orientation explains why foot rubs are erotic. Stimulation of the foot and toe region of the brain will affect the neighboring genital region causing arousal.

Would that not in turn explain the foot thing

I don't see how because a foot fetish is an attraction to someone else's feet, as in "feet that don't have a neighboring nerve connected to the same part of the brain that controls said foot pervert's dong."

This is actually science related to the electrical impedances of nerve and brain tissue.

The connection between foot nerve stimulation and genital stimulation is a physical one that can (and has) been measured and reproduced. This response is nearly universal and affects men and women, unlike a foot fetish.

I think a better explanation for the fetish is that feet are a part of the body that is often covered and seen as generally dirty, giving it a taboo allure other non-sexual parts of the body don't usually have, but that's less neurology and more just my opinion. Lol

Edit: added the usually

I mean, if your partner gets turned on when you touch their feet I'd expect that to make you feel something too. But I do think your theory is compelling as well.
