Our Verdict. The Nike Zoom Pegasus 39 is both stiff and responsive compared to other running shoes that we tested, leading to a very supportive feel and a performance-oriented platform. The upper contributes to performance by being snug in the midfoot while narrowing in the toe-box to provide a locked-in feel.

You'll experience them all with Nike Zoom, our innovative and explosive cushioning system designed for speed and agility. The technology uses pressurized air and tightly stretched fibers to absorb impact and then snap back for fast movement and reduced stress on muscles, joints, and tendons.

All Nike shoes are packed inside a box with a certain label and tag. The colour and print of the box usually vary depending on the style but mainly the boxes revolve around the colors red, orange, and brown. The print on the box should have the size, serial number, and style, with a barcode.
