The new ASICS Gel-Cumulus 21 is a daily go to shoe designed to cushion and support your feet over long distances. Featuring a more accommodating forefoot fit, added underfoot comfort, and a softer landing, the ASICS Cumulus 21 is ready for the bulk of your miles. The new Cumulus features 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.
