Nike Air Zoom Structure 23
The Nike Air Zoom Structure 23 is a comfortable and stable running shoe that marks a significant overhaul for the collection.
Nike doesn't present the Structure 23 as a stability shoe for overpronation. Instead, like the Nike React Infinity Run Flyknit, it prefers to introduce it as a stable model for everyone. As a result, there's no longer a support system to aggressively reduce pronation. Instead, the walls on each side of the foot rise to guide the foot and make the wide platform even more stable. The stack height remains similar: 21 mm under the heel and 13 mm under the forefoot. However, the foam is much softer than before, which gives a lovely plush underfoot feel but limits the platform's bounce, according to the testers. Therefore, while the S22 was snappy and suitable for speedwork, the S23 seems a bit duller. This new configuration surprised the fans of earlier versions who criticise the lack of versatility of this new model.
As for the upper, the classic mesh is well ventilated though a bit thick. The fit is comfortable, and the lockdown effective. The heel counter is rigid, which can be a little uncomfortable if you have Achilles tendon problems. Also, runners with wide feet will be delighted: the Structure 23 is roomy, especially around the toes.
Finally, the outsole features a lot of rubber to enhance durability and increase traction. Nike did a good job there as, even with all this thick and sturdy configuration, the weight is reasonable. The shoe weighs 289 grams (10.2 oz)—40 g (1.4 oz) less than the previous model.
In short, the S23 represents a new beginning for Nike's Structure collection. As we often repeat, there's no scientific evidence to support the effectiveness of stability shoes, and it seems logical that in 2020 brands are exploring new concepts. Overall, this model gains in comfort but loses some pop, making it mostly suitable for quiet daily training.

Model: Nike Air Zoom Structure 23
- The outsole of the Nike Air Zoom Structure 23 is equipped with hard rubber under the heel that protects the platform from wear and tear, especially the midsole that’s more fragile. This platform also aims to provide adequate traction on urban surfaces.
- Blown rubber is a soft compound found under the toes that allows good flexibility to adapt to the movement while running. This element is beneficial at toe-off.
- The midsole uses regular foam to offer a comfortable and soft underfoot feel.
- Also, the Zoom Air consists of a unit filled with pressurised air under the forefoot. It enhances shock dispersion for a more comfortable and snappier ride.
- The crash pad under the heel is a special zone designed, according to Nike, based on the data from hundreds of athletes. It aims to facilitate smooth heel to toe transitions.
- The upper of the Nike Air Zoom Structure 23 features an engineered mesh with synthetic leather and textile materials. It comfortably and safely locks down the foot inside the shoe while ensuring airflow, especially in the summer.
- The woven heel improves foot support by avoiding heel slippage.
- Finally, the plush tongue and collar keeps the foot secure and comfortable.
