Good to know

The Newton Motion 9 looks and feels similar to its immediate predecessor, the Motion 8. But this updated model is purposefully made to be lighter, more seamless, and more breathable than what was given before. The performance-ready combo of the cushioned platform and external pad continues the legacy of this well-received series from Newton.

Runners are treated to a true-to-size in-shoe experience with the Newton Motion 9. Those who desire optimum comfort can use their usual sizing expectations when vying for a pair. Still, it is highly recommended to try the shoe personally or get ahold of user reviews that cover the aspect of size to fully enjoy an accommodating run.

When it comes to the fit, the details that work together to ensure comfort and security are the form-welcoming fabrics of the silhouette, the foot-shaped outline of the Adaptive Fit construction, and the semi-curved shape of the platform.

The outsole unit of the Newton Motion 9 the s.h.a.r.c. (super high abrasion rubber compound), a layer that protects the bottom part of the midsole from the potentially damaging nature of the surfaces. It is also responsible for delivering traction over the surfaces.

The Action/Reaction™ Technology is made up of five active lugs near the ball of the foot. These individual nodes press into the platform when pressure is applied to them, then spring back to their original place when the same force is removed. This mechanism energizes the toe-off phase of the step while also banking on extra traction due to its rubber material.

Newtonium foam serves as the cushioning unit of the Newton Motion 9. This full-length piece is tasked with delivering a supportive plane on which the foot can rest. The responsive nature of the foam itself is meant to enable the vigor of the step.

The medial side of the platform features a high-density wedge. The purpose of this feature is to correct overpronation and maintain a neutral gait that doesn’t collapse or cause discomfort.

The ETC Sockliner offers antimicrobial protection and extra oomph to the underfoot experience.

The upper unit features engineered mesh. This textile resembles woven cloth. It even has a seamless and breathable design to prevent hot spots and chafing. Cloth-like uppers are trendy accouterments that grace many running shoe series like the Hoka One One Bondi.

The Adaptive Fit upper unit configuration follows the natural shape of the foot. The curved structure widens near the forefoot section to accommodate toe-splay while the snug heel part aims to steady the frame of the foot and keep it from exiting the interior chamber unexpectedly.
