The Nike Air Zoom Pegasus 38 are women's running shoes made for runners with medium or light weight and neutral support. They are perfect for everyday racing over all distances.
The midsole ensures exceptional cushioning and responsiveness thanks to the combined work of Nike React technology, with a greater amount of foam, and the Air Zoom unit positioned in the forefoot. The upper has been revised and made more breathable and comfortable, while the new lacing system, with eyelets connected directly to the midsole, guarantees a perfect fit.
Because the classic Pegasus fit is back, the comfortable one typical of the versions of the past, but revised, in this new edition, to give a touch of novelty to a timeless icon!

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.
Air
Nike  Air units work by trapping air molecules inside a durable urethane  shell. With each footstrike, the air unit compresses to reduce the force  of impact, then immediately recovers its shape to be ready for the next  landing. Nike Air units are built to last, so the cushioning properties  hold steady for the life of the shoe.
Nike React 
Nike React foam cushioning offers support and reactivity. Resistant and soft at the same time returns all the energy you put in every step.
