Nike Air Zoom Structure 21 Running Shoes

Automatic translation Original description available here

Nike’s Air Zoom Structure 21 are outstanding training shoes, ideal for pronator runners in the mid-to-high weight range (up to 85 kg). Weighing less than 300 grams and sporting an excellent functionality, the Structure 21 will also be useful for runners who want more step stability in low-effort competitions.

In the Structure 21’s midsole you will find an advanced combination of technologies at your service; an Air Zoom unit in the heel area, Phylon cushioning along the forefoot and the foot’s outer side and Cushlon ST offering high compression in the inner side. With this triad, Nike offers in these shoes what they call Dynamic Support, helping your feet to not prone excessively as you run.

The outsole, flexible and texturized with a very advanced lattice of pentagonal cleats, increases support and helps you maintain a healthy tread dynamic. In addition, its Dynamic Fit upper - made up of Flywire cables with an internal arc-shaped band that provides a smooth sleeve-like feel around your feet - prevents slipping and provides a great, snug fit. The upper uses an extremely lightweight version of Flymesh to keep your feet cool and to protect them from elements and abrasion.
