FACEBOOK pervs are swapping "candid" photos of women's feet snapped in public places without their permission.

The Sun uncovered two dozen "candid feet" pages and groups in just a few minutes, some of which have tens of thousands of followers.

Hundreds of photos of women's feet taken in public places have been uploaded to Facebook.

These photos – some of which we've included, but pixellated to protect the women's identities – show women going about their business in shops or on buses and trains, with no idea they're being preyed on by sickos.

Several of the pages seen by The Sun even had photos that revealed the faces of women.

Worse still, Facebook makes no effort to hide the clearly sexual pages, which anyone – including children – can find in seconds.

Pervy fans of the pages leave comments like "I want to lick them feet" and "Can I tickle and worship those beautiful feet?".

Photos of unwitting women were described as "sexy", despite the women seemingly having no knowledge that a photo was being taken.

One page we found was dedicated to candid photos of "smelly feet" specifically.

We spoke to Joe, who runs a page dedicated to candid feet photos in the West Midlands, who explained that he doesn't see the problem with swapping candid foot photos.

"It's not right to share pics without consent but they're only feet," Joe told The Sun.

He added that there's "no harm in candids, as long as it's a feet pic and doesn't show a face".

Joe explained that he enjoys "soft soles and a nicely shaped foot/feet", and looks out for "painted toe nails, toe rings, anklets".

He said it doesn't matter if the foot is "bare or in sexy footwear", and said: "I've loved women's feet since I was 12. I guess it's just preference."

But not all foot fans agree that it's fine to snap candid photos of women's feet in the streets.

Christian, the owner of a legitimate "foot fetish" fan page on Facebook with no candid photos, slammed the practice.

"I don't feel it is right – I see it as infringing," he told The Sun.

Facebook does restrict pornographic content on its website.

But its guidelines don't prohibit the posting of candid feet photos, despite the obvious risks.

Some pages we found identified very specific areas were photos were taken – including naming shopping centres – which could create a risk of stalking.

We spoke to Samantha Rennie, the executive director of UK women's rights charity Rosa, who slammed the pages as harmful.

"Taking and posting "candid" images of women without their permission says something very sad and pathetic about some people in our society," Samantha told The Sun.

"It also speaks to the reality of the culture of sexism in the UK. Objectifying women in this way is a form of abuse and harassment designed to intimidate women as they go about their daily lives.

"How would these people feel if it was their daughter, sister or mother being portrayed in this way? It has to stop.

"Which is why we've been giving grants to women's organisations through the Justice and Equality Fund, supported by TIME'S UP UK to tackle the culture of impunity around all kinds of abuse directed at women.

"By calling it out and not standing by, we can transform our culture so that women are free from this tedious - and harmful - daily aggression.

"We will all be better off as a result."

We've asked Facebook for comment and will update this story with any response.

Last year, The Sun exposed a huge cache of porn on YouTube that the tech giant had failed to take down.

We also revealed how Instagram sex hashtags were allowing perverts to circulate hardcore pornography on the app.

The UK government is preparing to roll out a nationwide porn block designed to protect children.
