The GEL-Kayano® 21 is updated with nothing but the best in ASICS technical innovation, featuring the next generation of FluidRide® and a ComforDry™ X-40 sockliner for the lightest and most luxuriously stable ride yet. Mild to moderate overpronators will enjoy a more comfortably secure upper, uniquely designed with a new heel construction that complements the premium FluidFit® upper and Heel Clutching System™. Weight: 10.9 oz. Heel Height: 22mm. Forefoot Height: 12mm.

Impact Guidance System (I.G.S®)

ASICS® design philosophy that 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.


ASICS FluidFit™ upper technology combines multi-directional stretch mesh with stretch reinforcements that adapt to the athlete's foot, creating a truly customized glove-like fit.

Heel Clutching System™

Exoskeletal heel counter provides improved support and creates improved heel fitting environment.

Rearfoot and Forefoot GEL® Cushioning Systems

Attenuates shock during impact and toe-off phases, and allows movement in multiple planes as the foot transitions through the gait cycle.

Dynamic DuoMax® Support System

This evolution of DuoMax® system enhances stability and support, with reduced weight and increased platform support.

Guidance Line®

Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.

Guidance Trusstic System®

This Trusstic System® integrates Guidance Line® construction for enhanced gait efficiency while providing midfoot structural integrity.

ComforDry™ X-40 Sockliner

This premium sockliner features higher rebound properties while providing excellent moisture management, high-level breathability, and anti-microbial properties.

Gender-Specific Cushioning

Women's models feature a lower-density top layer in the midsole, allowing female athletes to better enjoy the benefits of midsole compression.

Plus 3®

3mm of additional height on women's models helps relieve achilles tension.
