Nike Air Zoom Pegasus 42

The legend evolves. The Nike Air Zoom Pegasus 42 rewrites the playbook with a first-of-its-kind curved, full-length Air Zoom unit that mirrors the geometry of Nike's elite marathon racing shoes. Combined with ReactX foam, it delivers 15% more energy return than the Pegasus 41 — making every stride feel smoother, springier, and more propulsive.

What's new in the Pegasus 42:

• Full-Length Curved Air Zoom Unit — For the first time in Pegasus history, a single curved Air Zoom unit runs heel-to-toe, enabling a fluid, rolling forward motion that mirrors Nike's top racing shoes.
• ReactX Foam Midsole — 13% more responsive than standard React foam, with a 43% reduction in carbon footprint. Better for your run, better for the planet.
• Roomier, Accommodating Fit — Built on a modified last with a wider toe box and forefoot, encouraging natural toe splay without feeling loose.
• Extra Forefoot Cushioning — 3mm of additional cushioning under the forefoot gives you a springier toe-off without raising the stack height.
• Breathable Engineered Mesh — Double-layered mesh upper with integrated Flywire midfoot system for a secure, ventilated fit that holds firm mile after mile.

Whether you're logging daily miles, building toward a PR, or just starting your running journey, the Pegasus 42 is built to carry you forward. The workhorse, reborn with wings.
