barefoot running

So I went out and bought some Vibram 5 fingers, the shoe that simulates running barefoot. It looks strange but is supposed to help prevent injury and create a more proficient workout. Read more about them here:

I have never tried these before but have read enough about them to give them a try. They've been sold out or on back order for nearly half-a-year so they must work, right? I know some people that have used them with much success. I will see how the next few weeks go with them!
