Women's Self Defense Using Spike High Heels is a growing group of women who demonstrate “how to humble dangerous, arrogant men in threatening situations with spike high heels as weapons." In other words, “Kick them in the groin very, very hard.”
The actors in the Women's Self Defense video productions leave no room for men to be mean. While this could potentially be a very good way to defend yourself, I personally think this has more to do with fetish and role play. It does not help that the girls in the pictures look like Berlin hookers. The second clue is the site’s statement that all models are over the legal age requirements.
