Reinvigorate your stride with the Nike Air Zoom Pegasus 37. Delivering the same fit and feel that runners love, the shoe has an all-new forefoot Air Zoom unit and Nike React foam for maximum cushioning and responsiveness. The result is a durable, lightweight trainer designed for everyday running. A midfoot band adapts to the size of your feet, keeping you comfortable and secure with every step. A translucent upper has the look of speed and is made to help your foot while you run. Mesh throughout adds to that transparent look while helping promote ventilation. Nike React foam at the midsole is lightweight, springy and durable. More foam means better cushioning without the bulk. An Air Zoom unit at the forefoot is twice as large as previous versions, delivering more bounce with every step. It's top-loaded to be closer to your foot for better responsiveness.
