Responsive cushioning in the Pegasus 42 provides an energized ride for everyday road runs. Experience power in every stride thanks to the propulsive feel 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-off.
ReactX Foam Midsole
ReactX foam is 13% more responsive than previous React technology.
Breathable Upper
Lightweight mesh is softer and more breathable than earlier iterations, helping your feet stay comfortable.
High-Abrasion Rubber Outsole
Lighter than previous models, an updated Waffle outsole delivers traction and flexibility with high-abrasion rubber and flex grooves.
Wide Toe Box
We updated the fit to give you a little extra room at the toes and forefoot compared to the 41.
