Your workhorse with wings is the Nike Air Zoom Pegasus 37. With 37 years and millions of miles of experience, the legend lives on. Nike's most trusted running shoe flies into the future with new technology and a new look. The Air bag is directly under your forefoot, and the amount of Air is adjusted between men's and women's shoes, based on the preference of each. 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.
