Nike Air Pegasus+ 28 BreatheMany consider the Air Pegasus the foundation of Nike's running shoes. The Pegasus originally debuted in 1983 and was designed for the "everyday runner," but since then they have been upgraded many times. The Nike Air Pegasus+ 28 Breathe features an ultra-breathable mesh upper that enables moisture management. They also feature strategically placed no-sew overlays, Flywire technology, Nike Zoom unit in the heel, and a rubber outsole with flex grooves.
