Footfetish means a special devotion or passion to feet. Statistics prove that foot fetish is more often common to men then women. People with a footfetish love to worship feet. For Example they suck toes, lick soles or kiss the back of the foot. Worshipping feet is not rarely part of dominant role plays and shows the submission to another person. The person who worships needs to kneel to be able to kiss, worship or show his or her submission. So many foot fetishists are submissive minded and like to play dominant role plays.
By the way: The smell of a foot is very often important to a foot freak.
