I like feet. I don't know why. What I do know is that condescending shit like in OPs image turns me the fuck off. I also have a thing for one piece swim suits.
I also know that, historically, in times when STDs and whoredom have been on the rise, men have always acquired foot fetishism. Maybe it's an evolutionary trait, to look at the feet first which are more likely to be neglected. If the feet are in a terrible state, chances are, the cunt will rot your dick off with syphilis.
Coincidentally, rise of STDs and whoredom, inflation of women's egos and faggot tolerance, are some of the heralds of civilization collapse. So wide spread fetishism is most likely a symptom of the general decadence of our civilization. We're in the Kali Yuga. Again.
