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 Systems 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.
