SMOOTH TRANSITIONS. LIGHTWEIGHT STABILITY.
Lighter and stronger than the previous version, the Nike Air Zoom Structure 21 Men's Running Shoe provides the stability and support that made it a favorite. Softer, lightweight Flymesh material helps keep your feet cool, while responsive Nike Zoom Air cushioning in the forefoot gives you a snappy, springy feeling underfoot.
The one-piece Flymesh fabric provides more ventilation throughout the top of your foot. This version of Flymesh has lighter materials that still provide strong support.
