Im wondering if any of your girls would like to get their feet toes or soles somehow gently run over by a tyre of a car or bike. It would be a nice 'endurance' theme in addition to fire and glass walking.
It would be a first, as no other sites have attempted this before.

Hi Dave 8000,
You mention that no other site has done this so called trick with a car or
bike. To be honest with you am not sure whether any one will be willing
to take part in this! either gently or other wise. It all seems rather worrying
to me!

Hi Dave

I think it would be too dangerous for the girls, as it might result in broken bones. Walking barefoot toughens their soles, but not the rest of their feet, I don't think they could endure having a car or bike running over their naked feet... and it wouldn't be attractive at all if they get their feet damaged. Even with shoes on it would be dangerous.

Regards

I know you're not wanting to see the girls damage their feet Dave, but your request made me remember a Yahoo Group that shows pics of the results of girls who have had their feet run over, among other things. It's called Smashed Toes, and it's not a site for the squeamish at all. I only found a couple of the pics on there enticing, but anyway, if you want to see the more hardcore stuff, I could try to find the link to the Group.
