Running is your daily ritual, and nothing stops you from striding closer to your personal goals. Let the Nike Air Zoom Pegasus 39 help you power toward that finish line with its comfortable, intuitive design. Underfoot cushioning and Zoom Air units in the heel and forefoot add a spring to your stride as you transition from heel to toe while a supportive sensation helps your foot feel contained. Your trusted workhorse with wings is back. Time to fly.Total Comfort & Data-Backed Breathability: Extra padding at the tongue and collar helps your foot feel comfortable. Plus, we tested runners like you to find where cooling was needed most and placed engineered mesh—stronger and more flexible than regular mesh—throughout the upper using that data. The result is a shoe that's lightweight, breathable and durable.Supportive Steps: Flywire technology is integrated with a midfoot band for total support that helps keep your foot in place. Smooth Transition: Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. We paired it with 2 Zoom Air units (at the forefoot and heel) for an energized feel at toe-off. The result is a smooth transition from heel to toe. Rubber outsole provides traction while flex grooves throughout give you extra flexibility and a smooth feel on toe-off. We designed the heel to help optimize your landing, helping you easily transition from heel to toe. Tongue is separated from the upper to give room for different foot shapes. Reinforced toe tip adds durability. Reflective elements Not intended for use as Personal Protective Equipment (PPE)
