The Nike Pegasus 39 is designed to elevate your performance to new heights. It is lighter than its predecessor, the Pegasus 38, making it perfect for any season. With its supportive feel, your feet are kept secure, while the cushioning and double Zoom Air units (one more than the Peg 38) provide an extra boost to your stride. This trusted workhorse with wings is ready for take-off! To ensure your comfort, the shoe features extra padding at the tongue and collar. Its engineered mesh upper is stronger and more flexible than typical mesh, providing lightweight breathability. Flywire technology and a midfoot band work together to keep your feet firmly in place. The Nike React technology, a durable and lightweight foam, delivers a smooth and responsive ride. The forefoot and heel Zoom Air units provide an energized feel, while the heel shape and thick foam enable easy heel-to-toe transitions. Other features of the Nike Pegasus 39 include a tongue that is separate from the upper to accommodate different foot shapes, a waffle-inspired outsole for excellent traction, and grooves on the rubber sole to allow for unrestricted movement.
