Full-length responsive cushioning, sculpted to energize an icon.

Responsive cushioning and bounce with every stride. The Pegasus 42 is the ideal shoe for your everyday road runs. Discover the power in every stride thanks to the propulsive sensation of a curved full-length Air Zoom unit and a ReactX foam midsole. An updated fit gives you more space in the forefoot and toe box.

Full-Length Air Zoom Unit
Shaped to fit your foot, a full-length Air Zoom unit delivers a propulsive feel and Nike’s highest energy return from heel to toe.

ReactX Foam Midsole
ReactX foam is 13% more responsive than previous React technology.

Breathable Upper
Lightweight mesh is softer and more breathable than previous versions, providing optimal comfort.

Abrasion-Resistant Rubber Outsole
Lighter than previous models, the new waffle-pattern outsole offers incomparable grip and flexibility thanks to its ultra-durable rubber and flex grooves.

Roomy Toe Box
We updated the shoe’s shape to slightly widen the space in the toe box and forefoot compared to the 41.
