Top to bottom, Nike Flex RN 2018 Men's Running Shoe is built to flex. Its circular-knit upper stretches in key areas, while the dynamic heel design and molded tri-star outsole pattern work together for an adaptive ride that connects you to your run.
- Circular-knit upper provides strategic stretch and support.
- Dynamic Flywire cables deliver a locked-down fit.
- Tri-star outsole pattern enhances flexibility.
- Minimal heel design is made with soft foam to secure the back of your foot while allowing natural movement.
- Co-molded midsole uses a softer injected unit (IU) core foam directly underfoot and a slightly firmer injected unit (IU) carrier foam to deliver softness and support just where you need it.
