Nike Zoom Rival Fly 2 Women's Performance Running Shoes Pink Glow/White/Platinum Violet

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.
