Shoes Suck. Ok they are nice if you work construction or see Code Browns in a hospital but if you are one of those people who like to run…ditch your shoes. Why? Modern running footwear is designed for one purpose: to allow you to perform a powerful heel strike without crushing your leg…all at once, it just takes a little more time. They are also a nice way of fleecing you of your cash. Biomechanical analysis shows unshod running to be 2-5% more efficient than shod running. For sciency info checkout Sportsci.org. For info on transitioning to the barefoot running style give this a look.
