Design:

• Upgraded breathable engineered mesh upper
• Improved engineered mesh on the upper decreases weight and increases breathability
• Plush collar tongue and sockliner for a secure and comfortable fit
• MR-10 Last for a consistent fit (same as Pegasus 40)

In-Shoe Comfort:

• ReactX foam midsole surrounds forefoot and heel Air Zoom units for an energized ride
• All-new ReactX foam midsole is 13% more responsive than previous React technology

Durability & Traction:

• Signature waffle-inspired rubber outsole for traction and flexibility

Additional Details:

• ReactX foam is engineered to reduce its carbon footprint by at least 43% in a pair of midsoles due to reduced manufacturing process energy compared to prior React foam
