Updated with at least 43% lower carbon footprint and 13% higher energy return ReactX foam, the Nike Pegasus Easyon in Black/Anthracite/White offers better performance for both you and the planet. The Nike Pegasus Easyon features two separate Zoom Air units, one in the heel offering springy cushioning on impact, and another in the forefoot for a springy feel through the transition from landing to toe-off. A wider forefoot and heel width not only improves stability but gives more room to pack in a wider Zoom Air unit for increased power. A lighter and more breathable upper than before uses an engineered toggle to let you adjust your fit simply.
