The Adidas Ultra Boost Uncaged Triple Black may have won the Footwear News award for Best Sneaker of 2015—for the record, Complex ranked the Ultra Boost as the no.1 sneaker of the past year—but the Ultra Boost had the biggest impact for the brand. It pushed major units and gave adidas it’s biggest crossover hit since, well, it’s been a while. The best part about the sneaker is you don’t have to run off on the plug to get your hands on a pair. That’s the way sneakers were intended to be, and even the way Kanye envisioned his own line. And Between the Boost technology and superior Primeknit upper, it is the best running shoe turned lifestyle phenomenon since Nike introduced the Flyknit Racer at the 2012 Olympics.
Since the release of the Adidas Ultra Boost 3.0 Triple Black UK in 2013 adidas have been tweaking the technology through iterations like the Pure Boost and Ultra Boost, although the basic makeup remains the same after all these years. The Boost sole uses a material called thermoplastic polyurethane (or TPU) to form its bundle tightly packed sole nuggets. Just like the more traditional midsole material, EVA, TPU compresses under pressure for shock absorption – what’s unique about the adidas tech is the ability to instantly bounce back to its original shape. By moulding together lots of small capsules, they are allowed to ping back into shape quicker and easier than one big slab of sole could. The frisky foam is able to retain these properties despite temperature variation, being almost impervious to the elements, where EVA has been observed to stiffen in the cold.
Most trainer soles on the market today are made from an ethylene-vinyl acetate (EVA) plastic foam. The Adidas Ultra Boost White Crystal White uses a special thermoplastic polyurethane (TPU) to create the individual pods that make up the sole. These not only offer better energy return but also stay in the same state despite temperature changes. This means you still get the boost and flexibility in the cold and they don't go soft in the heat, unlike EVA.
The "Adidas Ultra Boost 3.0 Oreo Zebra 2017 Black White Ultra Boost" is a bold declaration. With so many different shoes on the market and so many different foot shapes and preferences, what works for one runner may not be the best for another. There has been a ton of hype surrounding the Adidas Ultra Boost running shoes, but how do they actually perform? The Active.com editors put them through their paces, and spoiler alert: We liked them.
