Providing long-wear comfort with an engineered upper and sole, the Nike Wmns Flex 2018 RN 'Atmosphere Grey' sneaker helps enhance running performance. Released in April 2018, the women’s runner is outfitted with a flexible, circular-knit construction. Foot-hugging Flywire cables incorporate into the laces for a locked-down fit, while dual-density foam works alongside the targeted rubber outsole to promote cushioned durability.
