Nike's longest-running franchise returns to keep you running longer. The Nike Men's Pegasus 42 Running Sneakers evolve the legend, delivering its most responsive ride to date with 15% greater energy return than its predecessor. A curved, full-length Air Zoom unit paired with a ReactX foam midsole provides a high-energy, supercharged feel for explosive toe-offs that propel you forward. This iteration features a refined, engineered mesh upper that is lighter and softer than before, wrapping the foot in breathable containment to keep you fresh through every mile.
