Open Question: what causes men to develop a foot fetish?

[feedcrawler]

I once met a guy and broke up with him due to a foot fetish. My sister just found out her bf has a foot fetish. It was surprising since her feet aren't that attractive. She has fat feet, she has bunions all over the soles of her feet, and she has ingrown toenails. She also has scars on both feet from surgury. He has even offered to use a pumice stone and lotions to make her soles more appealing since she is so self conscious of her feet. He also says odor doesn't bother him. How do men develop a foot fetish and do men with foot fetishes like feet in general even ugly feet?My sisters feet aren't hideous but she is heavyset so her feet are a little wider. The ingrown toenails and surgury scars aren't too noticable and her soles aren't completely covered with bunions. I'd say her feet are average looking to below average. I thought guys with a foot fetish are looking for nearly perfect feet.
