The Adidas Ultra Boost is the latest and greatest addition to the relatively young but already legendary Boost running shoe line. The shoe is the successor to the Boost shoe released only a couple of years ago, which has been worn by more than 20 marathon-winning runners -- three of whom clocked in among the top five race times in marathon history.
The Ultra Boost's midsole comprises 3,000 styrofoam energy capsules, about 20% more capsules than other energy-boosting running shoes on the market. Meanwhile, the stretch web outsole can expand by up to 10 millimeters when it hits the ground.
At $180, this shoe is affordable not only to professional long-distance runners but to recreational athletes looking to reach new levels of performance. The shoe also has a gorgeous design that makes it stand out, making it even more appealing.
Running shoes are no longer just something comfortable to wear that are suitable for running, but are increasingly expected to be performance-enhancing tools in athletes' arsenals -- the Adidas Ultra Boost certainly lives up to that philosophy.
