There's quite a number of Youtube videos on the subject of women painting with their feet, and also dancing barefoot in paint. I thought I'd start a thread with a list of them.
To start, here's an Indian dancer dancing in paint. The whole video is a close-up of her feet!:

Thanks for sharing, I have never heard of that before. My wife is an art teacher, I'll have to see if she's willing to teach me to paint with her feet

Yes, and let's see the results!

This video is for kids, but the presenter is an adult woman. And this may well be the best painted feet video I've ever seen!:
