The Flyknit Lunar2 'Grey Volt' was introduced in August 2014, alongside eleven other colorways. This particular design prioritizes lightweight breathability and long-lasting support for runners on both the track and street. Incorporating a Lunarlon midsole, the shoe offers springy and responsive cushioning, while the strong Flywire cables across the midfoot provide stability and a personalized lockdown fit. Additionally, the shoe features a pressure-mapped forefoot and reinforced rubber heel that distribute weight evenly and enhance durability, catering to the needs of runners.
