What do you get when you combine one of the toughest methods of training with one of the toughest materials? How about one bad ass shoe designed to crush any WOD. The highly anticipated Reebok CrossFit Nano 5.0 is finally here, and it has surely separated itself from it's predecessors as the toughest Nano to date. For it's fifth inception Reebok partnered up with Dupont, the makers of Kevlar (yeah, what they make bullet proof vests out of), to create a training shoe unlike anything you've ever seen. Wrapped in an all new 360° Kevlar Cage, right out of the box the Nano 5.0 is ready to handle anything you throw at it.
