adidas’ Ultra Boost revolutionised the runner game when it was released in 2015, and it hasn’t paused for breath since. This one is 4.0 spec, featuring an adaptable Primeknit upper that’s all-black to cloud with the white of the boost™ cushioned midsole. Midfoot caging adds support and nods to the brand’s iconic three stripes, while Torsion top stabilises your arch with every step.
