37 years and millions of miles later, the legendary Nike Air Zoom Pegasus 37 lives on with new technology and a new look. Nike React foam is now used to improve cushioning and durability. A new Air Zoom unit at the forefoot is twice as large as previous versions, delivering exceptional levels of responsiveness. The Zoom units in male and female models are tuned to different pressures so that the cushioning is just right. This workhorse with wings can handle any session you throw at it.
