Offering optimal cushioning, secure stablility, and an improved upper, the ASICS® Gel-Nimbus 15 satisfies the needs of runners ranging from the underpronator to the moderate overpronator. Combining multi-direcitonal stretch mesh with stretch reinforcements, FluidFit adapts to your foot, creating a truly customized, glove-like fit. The FluidRide midsole blends bounce-back abilites, cushioning properties, and lightweight durability, which creates a soft, propelling, and long-lasting step. Working together for enhanced gait efficiency, the Guidance Trusstic System and Impact Guidance System enhance the foot's natural gait from heel-strike to toe-off for superior performance. This helps provide a smooth, efficient running motion. Improving cushioning and adding anti-microbial properties, the ComforDry sockliner keeps your feet cool, dry, and fresher. Consisting of an exoskeletal heel counter, ASICS' Heel Clutching System teams with Personal Heel Fit technology, two layers of memory foam in the heel area, to improve support, comfort, and fit. This ensures that your foot remains snug and centered during intense activities. High Abrasion Rubber outsole provides long-lasting durability and terrain-ripping traction, allowing you to combine exploration and exercise. Wt. 9.4 oz.
