Whether you are training for the Boston Marathon or just looking for one of the best lightweight running shoes, the adidas Adizero Boston 11 brings race-day quality to everyday training. The adidas Adizero Boston 11 combines the ultralight Lightstrike Pro midsole material with the durable Lightstrike EVA foam to give you a responsive, lively and cushioned experience underfoot. The combination works whether you are doing your weekend long run or super quick speedwork. Built on top of a Continental rubber outsole, the Boston 11 provides both durability and traction so you can race around corners with ease. This shoe is tuned for speed with adidas ENERGYRODS; these plastic rods built into the midsole give you a propulsive feeling and limit energy loss. It allows the shoe to feel flexible, yet has support in key areas to keep you running strong all workout long. Plus, the slight rocker shape will roll throughout your run. The upper has been redesigned to make the shoe lighter and fit better than before—adidas changed the overlaps and used a new thinner and more breathable upper material to give you a speedier fit and feel. Designers added a heel tab to make the shoe easier to put on and take off. Now the upper is made with at least 50% recycled content, so you can feel good about wearing it. The adidas Adizero Boston 11 will give you a light and fast feeling every time you lace them up. This pair is lightly used, but well-cared for with less than 25 miles on the road.
