The UltraBoost 4.0 was built by designer Ben Herath and adidas who employed cutting-edge technology and biomechanics data. Through a comprehensive analysis of three-dimensional movement, the German Brand successfully developed a two-dimensional Primeknit material that conforms to the foot's motion. This results in a snug and comfortable fit resembling a sock. The April 2018 'Linen' model features a pink and white Primeknit upper, complemented by a beige midfoot caging system for added support. For optimal energy return, the shoe is equipped with a white adidas Boost midsole, and the heel is adorned with gold UltraBoost branding.
