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.
