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. Weight: 8.8 oz. Heel Height: 25mm. Forefoot Height: 12mm.
