The adidas UltraBoost 19 undergoes a remarkable expansion on the renowned running silhouette by incorporating advanced heritage technology into an energetic design. Launched in October 2019, this rendition boasts a dynamic grey and yellow Primeknit 360 bootie that seamlessly adapts to any movement. The addition of a 3D heel frame and a midfoot cage featuring the iconic Three-Stripes enhances stability during runs. Furthermore, a dual-density Boost midsole and a Torsion Spring-infused Continental Rubber outsole work in harmony to deliver an exceptionally flexible and smooth running experience.
