Asics GEL-CUMULUS 21 Performance Black/Koi Shoes

Go further than you thought possible with the men's GEL-CUMULUS 21 performance road running shoe by ASICS. Designed to cushion and support your feet over long distances, this shoe boasts FLYTEFOAM Propel technology for excellent bounce and energy. The combination of rear and forefoot GEL technology means you benefit from a level of shock absorption not available in many other shoes, while GUIDANCE LINE technology enhances your gait efficiency and the internal heel counter holds your foot in position no matter how far you go. Further support comes from I.G.S (Impact Guidance System) technology which enhances your natural gait as you move, and the EVA sockliner that molds to the shape of your feet for added comfort. The highly resistant AHAR rubber compound reduces wear at key impact areas of the outsole, making this a performance running shoe that you can really count on as you look to reach new levels. Ventilation is provided by the engineered jacquard mesh upper, so you can rest assured that your feet will remain cool even when your run heats up. Reflective details on the outside of the shoe ensure you'll be noticed, even at lower light levels. With this exciting new design of the GEL-CUMULUS 21 shoe in your running bag, you'll be able to take on those extra miles in comfort and style.
