Mostly a fantasy and some women find it strange while others enjoy having their toes sucked, licked and massaged.
The pedicured toes,smooth/soft soles and high arch on a woman's feet is sexually arousing.
There's a sexual attraction to feet because, feet are sometimes hidden as are other body parts. And when seeing just the curvey shape under a woman'e socks, one might feel curious, and wonder what they look like.
The attraction for feet starts at a young age.
Not all feet are attractive,if someone has a foot fetish, don't look around and assume any feet will be attractive to that person. Many people are embarassed to admit tier attraction for feet because they are not sure if the attraction is right.
"ew,that girls feet are weird looking, man."
*not any ol' feel are attractive to people with foot fetishes.
