Nike's Pegasus collection has been keeping runners running for decades, and every single year there are improvements. For the Men's Air Zoom Pegasus 37 Shield Running Shoe, Nike instilled solid water-resistance and seam-sealing for greater protection in wetter climates. Underfoot, a React attenuates shock at every step, and the grippy, water-shedding sole keeps solid footing secure on slick roads to help run with confidence.
