Nike Men’s Air Zoom Structure 21 Running Shoe
Lighter and stronger than the previous version, the Air Zoom Structure 21 from Nike is suitable for everyday training and as well as being a great looking shoe. It has been built to slow down the rate at which your foot pronates and with its new wider base, helps to promote a faster and much improved performance. This is mainly achieved through the Dynamic Fit technology helping to ensure a smoother transition and the triple layer foam offering all the support you need. Despite all the support and cushioning it still manages to remain as light as a feather. Flywire technology has been updated and along with the Flymesh upper provide support and a glove like fit for your foot.
- Dynamic Fit technology locks down the foot.
- Engineered mesh provides targeted ventilation and support.
- Dynamic Support system in the midsole provides a smooth transition.
- Full inner mesh bootie wraps the foot to enhance breathability and provide a sock-like fit. Notches on each side of the tongue allow for easy on and off.
- Compression-molded Phylon on the medial side and Cushlon foam on the lateral side are fused together to create a dual-density cushioning system.
- Zoom Air unit in the forefoot delivers responsive, low-profile cushioning.
- Honeycomb outsole pattern provides great multi-surface traction.
