Purchased brand new from Nike and tried in by my husband - never worn outside - he is a sneaker freak but these do not fit him well. In mint condition - no box- great pair of shoes - smoke free home, cat kept out of closets. The React Infinity Run 'Black' applies a simple color scheme to a performance runner engineered to go the distance. In addition to an upper that uses revised Flyknit made with three discreet layers for added strength and durability, the React foam midsole is fortified with a higher stack height and wider stance for a more stable ride. A high-traction rubber outsole provides sure footing through each stride.
