The Nike Zoom Structure 18 blends stability and cushioning together to create a versatile daily trainer for moderate overpronators. The Structure 18 utilizes a triple density material design in the heel and springy zoom air pockets in the forefoot to provide a supportive and responsive heel-to-toe transition. This model excels as a daily trainer but runners may find the springy underfoot feel suitable for tempo runs. 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.
As the lightest structure to date, Nike strives to strip the notion that support shoes need to be heavy and bulky (check out this video of the Structure 18 in action). At faster paces, when your stride is most efficient, testers found the lower density Phylon provided a smooth transition but during slower speeds, the other two layers hold up offering adequate support for significant overpronation. The stock fit post, located on the medial side of the midsole, seemed to give the Structure 18 a unique feel. Testers found it provided a very supportive ride, on the border of being classified a maximum support shoe, while still being versatile enough to accommodate a range of pronation levels. Another new feature of the Structure 18 is the stable ride sockliner, which integrates additional support through a denser material composition and a deep heel cup that works in unison with the triple density support system. Upon inspecting the sockliner, testers appreciated the extra cushioning it provided, contributing to the sensation of stability and cushioning during exercise.
In order to create a responsive and cushioned ride, the Structure continues with a forefoot loaded zoom air unit which acts like a spring to propel your foot forward at toe-off. In addition, the heel is built up to 27mm for substantial protection on cement and asphalt surfaces. While the heel lacks a zoom air unit in order to optimize the functionality of the dynamic support system, testers found the shoe to provide plenty of shock absorption for heel strikers. Together, the heel and forefoot create a soft yet responsive ride for long runs and daily training. Runners looking for a more protective and structured tempo shoe may also utilize the Structure because of its smooth energy efficient toe-off.
The introduction of the new Flymesh material further sets the Nike Structure 18 apart. The tightly wound design creates a soft texture that testers described as a more structured version of Nike’s popular fly knit material. Flymesh technology provides a breathable and seamless experience for added comfort during daily training.
How it Fits
While length is standard, testers noted the toe box height ran slightly low providing a shallow feel over the toes. The addition of dynamic fly wire gives the shoe an anatomical fit that provides excellent midfoot security. For runners looking for additional width options, the model comes in B, D, 2E, and 4E.
The Nike Zoom Structure 18 competes directly with the ASICS 2000-3, Brooks Ravenna 5, Mizuno Inspire 11, and Saucony Guide 8. Each of these trainers provide support for moderate overpronation and similar universal fits. In terms of ride, the Mizuno Inspire 11 is the firmest of the bunch. The Structure 18 and 2000-3 lean toward the firm side of the spectrum while the Ravenna 5 and Guide 8 are fairly soft. Although the Structure 18 is a bit more responsive that the previous version, runners seeking a supportive, uptempo trainer in the Nike line should check out the Zoom Fly.
