Nike Air Zoom Structure 23 Men's Structured Running Shoes Black/Metallic Silver/Volt/Anthracite

DYNAMIC SUPPORT
Dynamic support in the shoe's midsole provides the stability you need in an ultra-smooth ride, without the added weight or stiffness of a traditional medial post. It features more soft foam on the lateral side for cushioning on impact and more firm foam on the medial side for support.

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.
