Details
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.
