looking for sponsors in a micro niche: dirty female feet
 

yes, that's it, dirty female feet, hard for most of us to stomach it but I got the traffic for it.
so who has sites for it ?

Make your own site. :thumbsup

I can't stomach it. :) seriously
I can promote just about anything legal but building a website for it is a totally different story

there is a new site, but the feet are way too dirty (for me) so I doubt it will convert very well: dirtybarefoot.com

photoshop the feet with some black and you're good to go :)
