The Nike Flex 2017 RN 'Metallic Hematite' sneaker was designed with the needs of runners in mind. Its black construction, highlighted by metallic Swoosh branding, is composed of an ultralight, one-piece mesh for an adaptive fit. Flywire cables are integrated with laces around the midfoot for secured support. A Phylon foam midsole works alongside a flexible outsole to promote fluid motion through each stride.
