Made with a lightweight upper, the Nike Zoom Pegasus Turbo 2 is one of the top shoes of the manufacturer. With a lighter upper and dual-density foam, the shoes are made for the avid runner. Their full potential is reached when running outdoors. It’s hard to see their full potential while running on the treadmill. Out on the track or pavements, the shoes come with the ZoomX foam, Nike’s lightest foam.
