About the Nike Zoom Structure 21

Get up and running with the Nike Zoom Structure 21. Designed to accommodate over-pronating runners, this iteration of Nike’s stability running shoe is ultra-lightweight for free, natural and comfortable movement. The wrap-knit upper strikes the perfect balance of a secure fit, without being too constricting while the internal heel counter is supportive, providing a locked-in feel. Wearers also have the freedom to stretch their feet and toes with the roomy toe box.

The feet are also kept feeling cool and fresh with the knit-mesh breathable upper which optimises the circulation of airflow throughout the shoe. The crash pad and Zoom Air technology work together to absorb impact and spring runners forth into their next step. This makes for smoother transitions, ensuring that every stride is light and energised. The Nike Zoom Structure 21’s uses extend beyond running, based on reviews this pair can also be worn for walking, gym use and general exercise.

Nike Zoom Structure 21 vs 20

Overall, the Nike Zoom Structure 20 and 21 are responsive, well-cushioned and deliver an energised ride with smooth transitions. They are engineered to meet the needs of overpronating runners with plenty of midsole foam cushioning to keep wearers stable and support the collapsing arch. Additionally, both models also accommodate users with broader feet by offering wider width sizes for buyers.

However, the Zoom Structure 21 is significantly lighter than the 20. The heavier weight of the latter means that users are more likely to suffer from foot fatigue. The Flymesh upper of the 20th version provides structural support while promoting air circulation throughout the shoe. In contrast, the 21st iteration features a lightweight seamless wrap-knit mesh which envelops the foot and expands to mould around the shape of the foot for a second-skin fit.
