The Nike Lunarswift+: A lower-profile dynamic ridePart of the Dynamic Ride collection, the Nike Lunarswift+ Men's Running Shoe offers soft cushioning plus support that adapts to every stride. It features a lower-profile midsole than the LunarGlide for a slightly firmer feel underfoot. BenefitsBest for underpronated to moderately overpronated runnersNo-sew upper for reduced irritation and comfortLunarlon cushioning for a soft, bouncy rideDynamic Support that kicks in to provide the stability you needWeight: 306 grams (men's size 9) FitFor seam-free comfort, the Lunarswift has a stitchless, no-sew upper made of breathable mesh and synthetic overlays for targeted support. The robust heel counter gives you a snug, secure rearfoot fit. CushioningThe Lunarlon cushioning system is made up of a soft, yet resilient foam core that's encased in a supportive foam carrier for a lightweight blend of ultra-plush cushioning, springy response and support. SupportThe Dynamic Support platform in the midsole responds to a runner's changing needs, adapting to your stride throughout each run in order to give you just the right amount of support. For overpronators, the firmer, wedged carrier foam of the Lunarlon cushioning system limits excessive pronation when engaged--without the added weight or stiffness of a traditional medial post. Neutral runners won't activate this pronation-control feature, so the Dynamic Support platform simply feels like a well-cushioned, neutral shoe.
