The Pegasus Premium supercharges responsive cushioning with a sculpted Air Zoom unit and ReactX foam. It's our most responsive Pegasus ever, providing high-energy return unlike any other. Thanks to lighter-than-air materials, it decreases weight and increases breathability so you can fly faster. Breathable comfort We took our best practices from the Peg's past while still seeking a minimal feel without sacrificing durability and comfort. It's made from lightweight engineered mesh that helps keep you contained. All-Day Cushioning The full-length Air Zoom unit offers our optimal level of springiness underfoot, unlocking a level of speed and responsiveness that'll put pep in your miles. Responsive ride The ReactX foam midsole is 13% more responsive than previous React technology. Nike ReactX reduces the carbon footprint in a pair of midsoles by at least 43% compared with Nike React foam. More benefits * The modified Waffle outsole uses high-abrasion rubber to provide traction. * The carbon footprint of ReactX is based on a cradle-to-gate assessment reviewed by PRé Sustainability B.V and Intertek China. Other midsole components such as airbags, plates or other foam formulations were not considered. Product details * Weight: 325g approx.
