I personally don't believe there is such a thing as foot fetish. Most people who are attracted to a particular part of the anatomy or any specific body part is quite normal.

 If a man is attracted to the breasts of a woman, it isn't considered a fetish.  Since the beginning of time men have been attracted to not only women's breasts but to her eyes, buttocks, legs, and other parts of her anatomy too numerous to list.  We don't accuse or point fingers accusing such men as having a fetish.  Only when it comes to her feet do we say 'fetish'.

 The word fetish means:  Object believing to have magical powers.  Or, object of unreasoning devotion or concern.   I don't see anything in this definition that is negative or strange.  I believe that all reasonable men don't consider feet as magical.  I further don't believe that men become unreasonable at the sight of a woman's feet.  There is always the exception to the rule.
