When designing the new GEL-Nimbus® 17, ASICS opted for a little more revolution than evolution. Serious weight reduction takes center stage, with a nearly seamless FluidFit® upper that fits and feels like a runner’s dream. The new FluidRide™ midsole and extended Rearfoot and Forefoot GEL® Cushioning system improve upon the already famously plush and luxurious ride. Nothing but the best would do underfoot, thus a new top-of-the-line ComforDry™ X-40 Sockliner sits atop new full-length ComforDry™ lasting for the ultimate in cushioning and comfort. Weight: 8.8 oz. Heel Height: 25mm. Forefoot Height: 12mm.
