The NikeLab Mayfly Lite, a revamped version of the OG Mayfly designed to be lighter and last longer, dropped in a classic black and white color scheme for 2017. Up top, the black upper features ripstop material to keep things lightweight and water-resistant. Underfoot, a contrasting dual-density midsole and matching rubber outsole with durable pods at the heel and toe extend the shoe’s lifespan.
