New performance and new design for the Nike Air Zoom Pegasus 34 shoe. New double upper, even lighter and breathable. Dynamic Flywire cables combined with Dynamic Fit, placed inside the upper, guarantee a perfect mix of support and stability. Pentagonal piston rods are positioned side by side with respect to the previous version, to ensure better cushioning in contact with the ground and a soft and smooth transition. Suitable for runners with neutral support.
The new upper is lightweight and breathable, made in engineered Flymesh with a large groove in the front, helps to cool the fork during long runs. Flywire cables, internally, ensure a fit fit to fit the natural foot movements.
The midsole, made of premium Cushlon St foam, offers a soft cushioning, providing a solid and secure touch of support. The Zoom Air unit provides reactive support and cushioning.
The sole, featuring horizontal, vertical and pentagonal waffle pistons, guarantee perfect shock absorption.

Cushlon
The Cushlon midsole provides a durable, yet soft responsive cushioning.
Flywire
 Flywire helps provide ultra-lightweight support and comfort for your  foot. It gets its strength from thin nylon fibers strategically placed  on the upper of the shoe to hold the foot in place, helping to reduce  slippage during activity. This allows for a massive reduction in weight  because material is used only where it’s needed.
Zoom
Nike Zoom cushioning is part of the Nike Air family, and—like its  siblings—it’s lightweight and durable. Because Nike Zoom cushioning is  incredibly thin, it brings the foot closer to the ground and enhances  stability, especially during quick cuts and multi-directional movements.  After impact, the tightly stretched fibers inside the pressurized air  unit quickly bounce back into shape, providing a super-responsive feel  and improved awareness of the surface you’re playing on.
