These are filaments running connecting different parts of the upper and offering a more secure lockdown than even engineered mesh uppers.

The Nike Air Zoom Pegasus 39 also features the Flywire technology. The Air Zoom units, when placed correctly, offer great energy returns and reduce weight – after all, the units are filled with air which is lighter than any foam Nike might dream up. So, unlike the Nike ZoomX Vaporfly NEXT%, the foam of the Pegasus 39 will feel the same after 200 or so miles.Īs for the Air Zoom units, the Pegasus 39 now has two, doubling the amount its predecessor offered.

The former is a resilient foam – Nike's most resilient foam, in fact – that's built to carry you over long miles and designed to retain its good properties over long periods of time. There are two notable technologies involved with the Nike Air Zoom Pegasus 39: React and Air Zoom.

A translucent upper has the look of speed and is made to help your foot while you run.A durable rubber outsole and a reinforced toe help resist abrasion.
