The next step in the legacy of a Nike running legend is the Nike Air Zoom Pegasus 37. Updated cushioning and a classic fit and feel reinvigorate your stride. Its built to deliver the same fit and feel that runners love, and its all-new forefoot Air Zoom unit and Nike React foam maximize cushioning and responsiveness. The result is a durable, lightweight trainer designed for everyday running. Nike React foam midsole is lightweight, springy, and durable. More foam means better cushioning without the bulk. Zoom Air unit at the forefoot provides greater energy return, adding a pop to your step. Translucent upper looks like speed and is made to help your foot while you run. Mesh throughout adds to that transparent look while helping promote ventilation. Midfoot band adapts to the size of your feet, keeping you comfortable and secure with every step.
