Designed for runners with a neutral gait, the Nike Flyknit Lunar 1+ is an ultra-lightweight running shoe that delivers a dynamic fit with an excellent blend of cushioning and support. A one-piece upper with knit construction is made of polyester yarns that seamlessly integrate areas of high breathability, stretch, and support where you need it most. Flywire technology is ultra-lightweight, customizable through the laces, and wraps the foot for a dynamic fit. Low-profile knit tongue adds ventilation and comfort. Fitsole sockliner conforms to the shape of your foot, providing comfort and underfoot support. Pull-tab on the heel allows for easy on and off. Reflective elements remain visible in low-light conditions. Lunarlon cushioning system features a soft, yet resilient foam core that works with a supportive, bottomless foam carrier to provide support and plush, responsive cushioning. The firmer carrier foam core offers lightweight, springy response. Duralon blown rubber forefoot lugs deliver cushioning and helps encourage a more efficient, natural range of motion through toe-off. Flex groves add enhanced articulation flexibility, and a smooth transition. BRS 1000� carbon rubber along the heel contact zone gives maximum abrasion resistance and long-wearing durability.
