Happy Nanoversary! To celebrate the 15th anniversary of the iconic training shoe, Reebok set out to make the most comfortable version yet. These Reebok Nano X5 "Core Black/Grey 5" Men's Training Shoe have a dual-density midsole with firmer foam in the heel for stability and more responsive foam in the forefoot for comfort while running and jumping. A plush collar keeps the foot locked down and eliminates distractions. A decoupled, Metasplit outsole enhances runnability. <ul> <li>Designed for: Training</li> <li>Width: Standard</li> <li>Closure: Lace</li> <li>Upper material: Flexweave</li> <li>Lining material: Textile</li> <li>Midsole material: DualResponse EVA foam</li> <li>Outsole material: Rubber</li> </ul>
