Nike Men's Flex 2013 RN Running Shoe
Flexible, lightweight comfort is the best way to describe the Nike Flex 2013 Run running shoe. A stretched innersleeve with breathable overlay saddle gives the best in fit and ventilation. The soft Phylon core midsole provides great cushioning right where you need it, while an articulated Phylite carrier midsole adds flexible lightweight cushioning with great durability.
