The form provides foot stability

The Pegasus Premium supercharges responsive cushioning with a triple stack of Nike's most powerful running technologies: ZoomX foam, a sculpted Air Zoom unit and ReactX foam. Its the most responsive Pegasus ever, providing high energy return unlike any other. With a lighter-than-air upper, it decreases weight and increases breathability so you can fly faster.

• Stretchy circular-knit and breathable mesh on upper
• Full-length, superlight ZoomX foam provides springy cushioning.
• Full-length Air Zoom unit helps propel you forward like never before.
• ReactX foam midsole is 13% more responsive than previous React technology.
• Crafted for performance and planet, 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. The carbon footprint of ReactX is based on cradle-to-gate assessment reviewed by PR Sustainability B.V and Intertek China. Other midsole components such as airbags, plates or other foam formulations were not considered.
• Modified waffle outsole has high-abrasion rubber to provide traction.
