How about reviving barefoot extreme style video, where girls would push their feet to the max in some challenges(maybe even in form of actual challenge with price). Like for example girls jumping on thumbtacks or maybe staying on anthill) Something more hardcore then cigarettes or snow

This sounds fantastic

In terms of hardship a barefoot girl should be able to endure, nothing beats a long walk in fresh snow.

But there are a whole sister site dedicated to snow walking) I personally think that diversity is a key to enjoyment))

I agree! It would be fantastic. Actually Yuditza has been doing some extreme challenges such as glasswalking, bastinado and putting cigarettes out on the soles of her feet, which you can see on her YouTube channel:

It would be wonderful to have other CF girls do challenges too, good idea!

Yuditza is fantastic!!

Well, the sister site is good and I´m glad it´s still around, but in terms of real challenges it doesn´t provide that much.
Once I stumbled upon a clip made for Chilly Girls site. It featured a girl who was made walk in snow. Moreover, she was wearing only knickers and a sort of scarf. She was pacing to and fro, shivering, goose bumps everywhere. When her bare feet couldn´t take the cold anymore, she took off the scarf and stood on it to relieve the pain in her soles. At that moment she cast an appologetic look to the camera as if she wanted to say: "Sorry, guys, it´s more difficult than I thought."

A snow challenge I´d like to see: A Chilly Feet model is challenged to sweep or shovel snow in the pavement in front of her block of flats. Her task is to clean, say, 20-30 meters before being allowed to put her shoes back on or leave the street. Similarly, as the girl above, she has to do something when her feet become numb. She can stop working, take a jacket off and stand on in. Or sit down on it, and try to warm her toes in hands, etc.

How about that?

Actually sound pretty interesting Thought would be really hard to find model who is healthy enough to do this without problematic outcome) Yeah, extreme tests like this would be great to see

That idea certainly sounds interesting
