Searching for the twinkle in her eye to tell if she is head over heels in love with you? Forget the head for now, a researchers advises. It's time you turn your attention towards her feet.
The research says the way to tell if a woman likes a man is to look at her feet.
It is believed that our feet gestures are the most powerful form of body language because we are less conscious of what we are doing with them.
As for how to know if a woman has a thing for you: if the female moves her feet away from her body while giggling, to adopt a more open-legged stance, then she is attracted to you. But if her legs are crossed or tucked under her body, then you should forget about her.
Bad news for women: the rules do not apply to men, reports The Telegraph.
Professor Geoff Beattie, one of Britain's leading psychologists, made the findings after examining how people move their feet in response to different situations.
Prof Beattie, who is Dean of psychological sciences at the University of Manchester, said: "Whilst people might know what their facial expression or hands might be imparting, they will often have no idea whether their feet are moving or the messages their feet are sending out.
"People can mask smiles, or mask what they are doing with their eyes, but feet are actually a bit easier to read because people don't know what they are doing with them.
"The secret language of feet can reveal a great deal about our personality, what we think of the person we're talking to and even our emotional and psychological state, they are a fascinating channel of non-verbal communication."
He added: "If you are meeting someone for the first time, laughter is not necessarily a good thing - people can be laughing at you, or with you.
"If a woman's feet move when she laughs, it is one of the most powerful signals that she likes you.
"If they are crossing the feet, or crossing the legs - not good."
The research compiled on behalf of shoemakers Jeffery West also claimed that if a man is nervous, he will show his feelings by increasing his foot movement. Women however, do the opposite, and keep their feet still.
