Responsive full-length cushioning sculpted to energize an icon.
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.

Greater toe spring than previous model due to an updated silhouette that increases the curve of the toe box
Full-length Air Zoom unit compared to forefoot and heel units in previous models
We sculpted our full-length Air Zoom unit to deliver a propulsive feel and Nike's highest energy return from heel to toe-off.
ReactX foam is 13% more responsive than previous React technology.
An updated Waffle outsole delivers traction and flexibility with high-abrasion rubber and flex grooves.
Lightweight mesh is softer and more breathable than earlier iterations, helping your feet stay comfortable.
We updated the fit to give you a little extra room at the toes and forefoot compared to the 41.
