W Pegasus 42

Responsive full-length cushioning sculpted to energize an icon.

Responsive cushioning in the Pegasus 42 provides an energized ride for everyday road running. Experience unreal energy return with a curved, full-length Air Zoom unit and a ReactX foam midsole that’s lighter than the Peg 41. And, an improved waffle outsole with less rubber helps decrease weight without sacrificing trusted traction.

Full-Length Air Zoom Unit — Nike 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 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 — They updated the fit to give you a little extra room at the toes and forefoot compared to the 41.

What’s New? The full-length Air Zoom unit offers our optimal level of springiness underfoot. Waffle outsole has less rubber for a lighter design.

• Nike paired Nike ReactX foam (which they made lighter than the Pegasus 41) with the Air Zoom unit to give you a bouncy, springy sensation and an energized feel at toe-off.
• Signature waffle-inspired rubber outsole provides traction and flexibility. Nike reduced the amount of rubber as well, to reduce the weight of the overall shoe.
• Multi-zoned singled layer engineered mesh with haptic print and internal double layering helps you lock in.
• Plush collar, tongue and sockliner for a secure and comfortable fit.
