Nike Women's Lunaracer+Nike is always leading the way by incorporating innovative technology into their sneakers. The light-as-a-feather Lunaracer+ showcases a couple of Nike's latest achievements. The upper features Flywire technology that uses strategically placed nylon filaments on the upper to comfortably hold the foot in place. And, the midsole contains Lunarlite foam that is 30% lighter than standard Phylon, provides superior cushioning, and allows impact force to be evenly distributed. The Lunaracer+ is certainly the next generation of running sneakers.
