The Nike LunarEpic Low Flyknit 2 sneaker refines the first edition with subtle, yet impactful modifications to upgrade its multi-terrain performance. The 'Black' edition's single-piece upper features more prominent forefoot holes that direct airflow to a key area and a denser surface to enhance support. A fused heel overlay, midfoot Flywire cables and a dual-density sole composition stabilize the model when in motion.
