Run further than you thought possible with the GEL-CUMULUS 21 Knit running shoe from ASICS. The shoe is designed to help cushion and support your feet when running long distances. It features two midsole foams: one for lightweight softness and another that adds more spring to your step. This shoe also has rear and forefoot GEL technology for premium level shock absorption. Our GUIDANCE LINE technology helps you run more efficiently, while the internal heel counter holds your foot in position for added support. The flexible knit upper provides a comfortable fit and a more personalized feel. This feeling is exhibited because of the sockliner that molds to the shape of your foot for added comfort. The GEL-CUMULUS 21 Knit comes with a durable outsole that reduces wear at key impact areas while reflective details on the outside of the upper boost your visibility in low light conditions.
I.G.S (Impact Guidance System) Technology ASICS design philosophy that employs linked componentry to enhance the foot’s natural gait from heel strike to toe-off.
Guidance Line Midsole Technology Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.
FlyteFoam Midsole Technology Our FlyteFoam technology provides exceptional bounce back and responsiveness no matter the distance, utilizing organic super fibers to help reduce packing out that traditionally happens with softer, low density foams.
