The Pegasus Premium supercharges responsive cushioning with a triple stack of our most powerful running technologies - ZoomX foam, a sculpted Air Zoom unit and ReactX foam. It's our 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 fast. Breathable Upper - Circular knit upper helps keep you cool mile after mile. Responsive Cushioning - ZoomX foam in the midsole and ReactX foam in the heel create a new cushioning system for high energy return and peak responsiveness. Sculpted Air Zoom Unit - We sculpted a full-length Air Zoom unit so you can use the power of Air from heel strike to toe off.
