Nike Pegasus 39 Men's Road Running Shoes Let the Nike Pegasus 39 help you ascend to new heights. 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. Engineered mesh—stronger and more flexible than regular mesh—throughout the top provides lightweight breathability. Supportive Steps Flywire technology integrates with a midfoot band for 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 optimizes landing, helping you easily transition from heel to toe. We paired it with thick foam for a responsive ride. The tongue, separated from the upper, gives room for different foot shapes. Waffle-inspired outsole gives you excellent traction. Grooves on the rubber sole let you move freely.
