When it comes to running, going the extra mile isn't just a figure of speech. Whether it's morning exercise or intense training, a daily regimen of training miles, combined with ordinary movement throughout the day, demands a lot from a running shoe. With running comfortably for longer in mind, the 880 was built to provide consistent performance for the neutral runner. The Fresh Foam 880v11 represents a new generation set-up of the silhouette's workhorse reliability with the smooth transitions of a reimagined dual-layer midsole. The top-bed foam and Fresh Foam underfoot construction displaces heel impact and offers a responsive approach to cushioning. A plush, engineered mesh upper is infused with strategic zones of breathability and support. With the 880's 360-degree approach to comfort, you can keep going longer.
