Nike Air Zoom Pegasus 39 Men's Road Running Shoes ENERGIZED FOR MILES. Running is your daily ritual, with every step taking you closer to your personal goal. Let the Nike Air Zoom Pegasus 39 help you ascend to new heights, whether you're training or jogging, with its intuitive design. More lightweight up top than the Pegasus 38 and ideal to wear in any season, it has a supportive sensation to help keep your feet contained, while underfoot cushioning and double Zoom Air units (1 more than the Peg 38) give you an extra pop to your step. Your trusted workhorse with wings is back. Time to fly. Total Comfort Extra padding at the tongue and collar helps keep your feet feeling comfortable. We also placed engineered mesh—which is stronger and more flexible than regular mesh—throughout the top for lightweight breathability. Supportive Steps Flywire technology is integrated with a midfoot band for total support that helps keep your feet in place. Snap, Run and Pop Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. We paired it with a Zoom Air unit at the forefoot and the heel for an energized feel. Smooth Transitions The heel shape is designed to optimize landing, helping you easily transition from heel to toe. We paired it with thick foam for a responsive ride. Tongue is separated from the upper to give room for different foot shapes. Waffle-inspired outsole gives you excellent traction. Grooves on the rubber sole allow for natural motion.
