The Nike Flex RN 2018 running shoe delivers great connection between the foot and the ground. Featuring an easy fit with a circular-knit construction, the shoe allows the foot to flex and splay naturally. Flywire cables integrate with the laces for a dynamic lockdown and a dual-density foam midsole provides lightweight cushioning. Sections of the rubber tread form a honeycomb pattern at high-wear areas to enhance durability. This Nike Flex RN 2018 colorway comes in black and white.
