I am all for Barefoot technology. Takes a few weeks to get use to. But once you do it with the proper form its almost like your legs are seperate from your body. You can totally crank and your knees will never be sore.
I like the Nike Free series. The Five fingers are good but you look like a complete dork and say goodbye to the fuck me stares you get from the hot chicks at the gym when wearing five fingers.
