Advice for Road Runners:


The Structure is designed to provide a responsive underfoot feel and will work well for steadier-paced to faster-paced running. The midsole is a firmer EVA and a Zoom Air unit in the forefoot adds responsiveness. This helps create energy return to help move a runner forward at quicker paces.


Data from hundreds of runners helped designers create a new heel construction. The new geometry provides extra cushioning for heel-to-toe transitions, providing a slightly plusher underfoot feel than previous models. This is beneficial for runners using this shoe for slower-paced runs. The upper is highly ventilated and has perforations at the forefoot and midfoot to make it is breathable as possible.


Key Features:


  • Drop: 8mm
  • The upper is highly ventilated and has perforations at the forefoot and midfoot to make it is breathable as possible.
  • A Zoom Air unit in the forefoot offers responsive cushioning.

The Nike Air Zoom Structure 23 will suit runners who like a lightweight, responsive and springy underfoot feel.


Shoe size is a personal preference and everyone's feet are different, but we want to ensure you avoid any pain or discomfort from bruised toenails, rubbing, blistering or pins and needles. Your running shoes should have enough width to allow you to spread your toes and should have some space at the front (we recommend having a half to one thumb's width of space from the end of your longest toe to the front of your running shoes). This usually means that your running shoe will be at least a half size bigger than your regular shoe size though this can vary from brand to brand.
