Product title: Reebok Women's Crossfit Nano 3.0 Training Shoe
Product description: Introducing the Nano 3.0, our most versatile training shoe ever constructed. The evolution continues with a Dual Density platform that provides the perfect combination of forefoot cushioining and heel stabilization. We added more flexibility and protection to the outsole with Metasplit grooves and RopePro wraps on the medial and lateral sides. We carried the innovation into the upper with a new DuraCage construction for the ultimate in protection and lightweight support. Now, you are ready to take on the toughest workouts., Reebok was founded for one of the best reasons possible: athletes wanted to run faster. So in the 1890s, Joseph William Foster made some of the first known running shoes with spikes in them. By 1895, he was in business making shoes by hand for top runners; and before long his fledgling company, J.W. Foster and Sons, developed an international clientele of distinguished athletes.
