Made for rainy days, the Nike Air Zoom Pegasus 34 Shield Men's Running Shoe features an updated, lighter Flymesh material with a water-repellent finish. The tried-and-tested cushioning and support runners have come to love remains. Secure Fit Flywire—incredibly strong cables—works together with the laces to wrap the arch of your foot for snug support, helping to keep the shoe in place as you move. A firm heel cups your heel for added stability. Water-Repellent The one-piece Flymesh fabric upper has a DWR (durable, water-repellent) finish to help keep water out. It's still lightweight and breathable to help keep your feet from overheating.  Breathable Protection A breathable membrane lines the inside, helping block moisture while allowing air to flow, keeping your feet from overheating.
