Step onto the trail with a little extra stability and protection when you're wearing the Pearl Izumi Women's EM Trail M 2 Trail Running Shoe. As you float down rock peppered trail and descend steep gullies, this stability shoe helps your foot stay centered by utilizing a combination of soft foam cushioning and a bi lateral stability support located under your midfoot. One of the most unique features of this shoe is the E:Motion midsole, a bit of engineering that gives this shoe a dynamic drop heel forefoot height that's lower at initial contact and higher when you roll off your toes. E:Motion results in a more fluid transition from heel to toe and a more natural stride when you're picking your way through technical, off road terrain. For training, racing, or everyday running, this stability shoe helps you flow across miles of trail without skipping a beat.
