The upper of the UltraBoost 4.0 boasts a fourth-generation Primeknit construction, setting it apart from previous models. This iteration deviates from the previous approach of implementing tonal branding, opting instead for eye-catching contrasting white stripes on the side panels. The responsive Boost midsole not only offers exceptional comfort but also provides impressive energy return. To ensure enhanced traction, the Stretchweb outsole and Continental Rubber have been integrated into the design. With its cutting-edge construction and advanced features, the UltraBoost 4.0 is the perfect choice for those seeking both style and performance.
