The ISO Series of shoes are engineered to make you want to run. ISOFIT consists of a soft inner sleeve and floating support cage that combine to create a dynamic fit system that adapts to the shape and motion of your foot. PWRGRID+ provides more cushioning than standard midsoles while maintaining fluid transitions for a smooth ride. A Zealot uses these technologies in a lighter weight and lower profile. 57gm lighter than the Triumph and built with a 4mm offset, runners will love how light, fast and cushioned it is. Features: *Seam-free toebox provides great comfort *Reflective synthetic at collar *High-elastic sockliner *SRC Impact Zone provides durable shock absorption at impact *Deep forefoot grooves provide flexible feel *iBR Plus provides a soft, responsive ride *XT-900 carbon rubber for traction
