The best-selling highly anticipated super trainer is back for the second edition! Known for its lightweight comfort, performance and versatility from daily training, long runs to tempo work and even race day. ASICS has updated the design and construction with a new one-piece woven engineered mesh for a stretchier and more comfortable fit. The midsole features FF Turbo Plus foam (same used in Metaspeed race shoes) and a bottom layer of FF Blast Plus Eco. The outsole is now made with AHARPLUS.
