If we only made one running shoe, that shoe would be the 1080. What makes the 1080 unique isn't just that it's the best running shoe we make. It delivers the top-of-the-line performance of the best running shoe we make to every kind of runner. Whether you're training for world-class competition, or catching a rush hour train, the versatile application of the 1080's technological features allow you to do something more: more miles, more often, more comfortably. The Fresh Foam X 1080 Unlaced fine tunes the cushioning, weight, and flexibility ratio that makes the 1080 so adaptable to the stresses that occur during the course of every run. Signature Fresh Foam X cushioning technology is paired with a lightweight, engineered knit upper, focused on breathability and stretch, and strategic supporting elements.
