As dependable as shade on a cloudy but piping hot summer day, the Asics Men's Gel Nimbus 18 Running Shoe is built to provide run long comfort, whatever the mileage. Outfitted with a nearly seamless FluidFit upper, this shoe uses multi directional stretch mesh and reinforcements that adapt to your foot for a sock like fit. The ComforDry X 40 sockliner provides enhanced rebound cushioning, excellent moisture management, high level breathability, and odor resistant comfort. Underfoot, Asics added its ever popular Gel cushioning systems at the rearfoot and forefoot for supreme shock attenuation. The FluidRide midsole bounces back at each step and ensures long lasting cushioning. Guidance Line and Trusstic Systems work together to encourage a natural gait for neutral runners or underpronators. Additionally, this running shoe also features an exoskeletal Heel Clutching System for extra heel support and an improved fit.
