ASICS GEL-Kayano® 21 running shoes have been updated with the latest and greatest technologies available, starting with the FluidRide™ system that makes sure you experience luxurious cushion and stability. The secure upper is uniquely designed with a new heel construction that holds onto your feet for a glove-like fit. Ideal for mild to moderate overpronators.
Upper: FluidFit® combines multi-directional stretch mesh with stretch reinforcements that adapt to the athlete’s foot, creating a truly customized glove-like fit. Reflectivity is designed to enhance visibility during low-light hours. Heel Clutching System™ exoskeletal heel counter provides improved support and creates improved heel fitting environment.
Midsole: Gender-Specific Cushioning features a lower-density top layer in the midsole, allowing female athletes to better enjoy the benefits of midsole compression. Plus 3® adds 3mm of additional height on women’s models to help relieve Achilles tension. Impact Guidance System (I.G.S®) employs linked componentry to enhance the foot’s natural gait from heel strike to toe-off. FluidRide™ provides the ultimate combination of bounce back and cushioning properties with reduced weight and exceptional durability. Rearfoot and Forefoot GEL® Cushioning Systems attenuate shock during impact and toe-off phases, and allows movement on multiple planes as the foot transitions through the gait cycle. Dynamic DuoMax® Support System enhances stability and support, with reduced weight and increased platform comfort. Guidance Trusstic System® integrates Guidance Line® construction for enhanced gait efficiency while providing midfoot structural integrity. ComforDry™ X-40 Sockliner provides cushioning performance and anti-microbial properties for a cooler, drier, healthier environment.
Outsole: Guidance Line® vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency. AHAR® (ASICS High Abrasion Rubber) placed in critical areas of the outsole offers exceptional durability. DuraSponge® outsole enhances durability and cushioning in the forefoot.
