With its lightweight and buttery-smooth feel underfoot, the E:MOTION Road N1 v2 from Pearl Izumi is the shoe you'll reach for to tackle your next tempo workout or clinch that race day PR. The 3-D Seamless Print Upper Technology delivers a lightweight structure and upper integrity that promotes the lively feel you look for to propel you forward, fast. 1:1 Energy foam in the forefoot cushions upon impact and returns that energy back to the runner during propulsion. Full blown rubber in the forefoot and carbon rubber in the crash pad combine for premium cushioning and abrasion resistance. The EM Road N 1 v2 features an engineered E:MOTION midsole that is biomechanically tuned for a neutral to supinator running gait, creating a dynamic offset at 1 mm at initial contact to 4.5 mm at mid-stance. The heel stack height totals 19 mm and includes the midsole and outsole.
