The NRGY Neko Engineer Knit 'Green Glimmer' applies a stealthy color scheme to a streamlined runner built for all-day comfort. The engineered knit upper, woven with complementary black and grey yarns, rides on a solid black NRGY foam midsole that offers responsive cushioning from heel to toe. Contrasting pops of green highlight the branding hits that adorn the external heel clip, good for added stability at the back of the foot.
