We’ve engineered the compound to be 20% lighter, so you enjoy the same incredible energy return with less weight holding you back. An updated arrow-point pattern on the outsole lets your foot move from heel to toe quickly, enhancing the shoe’s springy feel. Now 20% lighter, our DNA AMP midsole technology lets your foot spring off the ground with each step for speedy, efficient energy return. We updated the Fit Knit Upper to provide a close-to-foot fit that’s lighter, softer, and more breathable than before.
