adidas has performed magic with the Ultra Boost by pulling a rabbit of maximal cushioning out of a relatively compact midsole that performs like a conventional, neutral trainer. Boost is a game changer for responsive cushioning that generates energy return over the long run without compacting or losing its resilient feel, even hours into a marathon or ultra. The upper is constructed seamlessly out of an airy stretch knit fabric. It accommodates wider feet but may feel sloppy for narrow-footed runners.
- boost™'s energy-returning properties keep every step charged with an endless supply of light, fast energy
- Bootie construction for comfortable fit
- Synthetic midfoot overlay and molded heel counter for added support
