Foot fetish has been defined as a pronounced sexual interest in the feet or footwear. For a foot fetishist, points of attraction include the shape and size of the foot and toes (i.e., long toes, high arches or slender soles, fat toes), treatments e.g.: french pedicure, state of dress (i.e., barefoot or clad in socks or nylons), odor, and any form of sensory interaction.
Aretifism is a sexual attraction to people who are or go without footwear, rather than to feet per se. This may include an attraction to dirty feet or soles.
I'm sorry, I know there are weirdos and perverts everywhere but it just bugs
