First introduced in 2008, Flywire engineering was strategically used in key areas to minimize its construction in order to allow the shoe to remain light and swift without the bulk. The Nike Flex 2018 RN 'Midnight Navy' sneaker utilizes the technology for supportive, yet flexible range of motion. It’s circular knit upper provides a lightweight, breathable fit, while the dual-density midsole works with the tri-star outsole for mobility.
