Featuring one of Nike's most responsive cushioning technologies, the Nike Zoom All Out Low 2 Women's Running Shoe is built for your fastest runs. A lightweight yet supportive construction helps you feel comfortable. Its understated design carries over seamlessly from your run to your day, no matter how quickly you need to transition. INCREDIBLE CUSHIONING A 3/4-length Zoom Air unit cushions from heel to forefoot for an incredibly responsive feel. As you move, the Zoom Air unit snaps back, returning the energy you put in. So, the faster you run, the more propulsive feel you get in return. LIGHTWEIGHT SUPPORT All-over lightweight mesh helps keep your feet cool by letting air flow. A firm structure in the heel cups the back of your foot for stability. TRACTION AND FLEXIBILITY Rubber on the outsole has a Waffle-inspired pattern and a crash rail for traction and flexibility. This crash rail is a rubber strip with small cuts along the side that helps smooth out heel-to-toe transitions and lets your foot flex.
