The medial support piece is firm, but it still flexes with the shoe and the other foam that surrounds it.
The ride is smooth and fast.
Nike Structure dumps its dual density midsole set-up for the first time in three years, and moves to a triple density set-up. The idea of using three different foam densities together in a stability shoe isn’t a new one; current shoes like the Brooks Adrenaline GTS 14 and Beast 14 feature that.
The Structure 18 is a great option for runners looking for one of the most supportive midsoles in its class while offering a moderately firm underfoot feel throughout the gait cycle.
It’s a big step for Nike, who have put a lot of effort into performance as well as looks. There is better support here than from the Zoom Structure 17 – it holds the foot better. This is a nice looking shoe.
I use them most during workouts on the track, but they can be easily worn on regular runs as well.
- Nike dishes out some serious modifications in the 18th iteration of the Structure. The most notable change in the shoe is the ride as it is back to its really stable form. Nike goes back to a tri-density midsole design to bring a nice balance of cushioning and stability. Foremost in the change of the ride is the presence of a very stiff EVA that extends from the heel to the midfoot to really curb the excessive inward roll of moderate overpronators.
- The outsole sees a major revamp also. In this version, there are now hexagonal lug patterns that are quite aggressive and large. Obviously, the aim is to enhance the grip on different surfaces. Besides the changing of the lug pattern, the material has been changed as well. The forefoot uses a softer blown rubber as opposed to the hard-wearing version used before. Midfoot to heel rubber featuring recycled rubber takes place of the BRS 1000. While durability remains just about the same, the new material is more friendly to the environment.
- Another contributing factor to the change of the Structure 18’s firmer ride is the incorporation of the crash pad to the outsole. There is lesser compression upon strike, so the runner no longer feels the squeeze upon landing.
- The smooth transition is enhanced by two slices of rubber beginning from the lateral side of the heel to just below the forefoot. As each strip is unbroken, the runner gets help through the gait cycle as weight is transferred quickly from the heel to the toes.
- The upper also introduces a new material that covers the entire shoe. It looks like a split between the Flyknit and engineered mesh. The beauty of this material is it adds structure and support to the upper minus the use of overlays, which are completely removed in this version, save for the printed Nike logo.
- Lastly, the Flywire cables appear in the 18th version of the Structure. From the midsole, they pass through tiny slits of the engineered mesh and are directly connected to the laces. Hence, a simple tug of the laces enables the cables to cinch and personalize the fit.
The fit of the Nike Air Zoom Structure 18 is still largely similar to the past model, except for a more forgiving forefoot due to the removal of all overlays. There is more room in the forefoot while the heel and the midfoot have very comfortable locked down feel. Shoe width ranges from narrow to extra wide in this shoe. Sizing runs true.
The outsole coverage is composed of two rubber compounds. Used in the forefoot is a soft blown rubber with the hard recycled rubber covering the rest of the shoe. Nike uses hexagonal lugs in the forefoot with deep flex grooves for traction and flexibility. The midfoot introduces a continuous design of rubber starting from the lateral side of the shoe going towards the opposite or medial side. Crash rails, these are called, and enhances the smooth transition of the shoe.
The outsole unit of the shoe has been modified in the Structure 22 to deliver more durability and reliable grip on varied surfaces.
The midsole uses a tri-density foam setup. On the lateral side of the shoe is a soft rubber while the inner side is made of ultra-stiff EVA. This very hard foam that extends from the heel to the medial side is the main factor that holds off overpronation. Nike also mixes parts of the midsole foam in the middle with the hard medial foam to prevent that jarring feeling from a very stiff medial support. The middle foam runs the length of the shoe for better transitions. In the forefoot and the heel, the patented Zoom Air bags are located. It provides that snappy response, particularly for midfoot and forefoot strikers.
The upper features the new engineered mesh that offers good structure as Nike removes the overlays in this model. It is distinctly a combination of mesh and flyknit with just enough give that the support is not constrictive. An inside toe bumper gives form and protection in an otherwise very minimal forefoot. The tongue and the collar are not very thick, but still very plush. Nike uses an internal heel stiffener to provide the stability. The Flywire cables that are connected both to the midsole and the laces hold the foot in security. For a little more cushioning, a plump and plush insole is included in the Structure 18.
