Back again, the Ultraboost is ready for long training runs, speedy races, and everything in between. Maxing out on Adidas' soft yet springy Boost cushioning, it provides top-of-the-line energy return to help you keep moving when you're going the distance. In addition to a whole lot more design technology, this shoe uses Tailored Fiber Placement in the upper to deliver stitched-in support that keeps your foot in place without adding bulk.
