The Ultra Boost 4 Tech Ink features a Boost midsole that is designed to provide superior cushioning and stability. The technology allows for excellent energy return, which helps reduce leg fatigue while walking and exercising. The shoe has a Tech Ink colorway with Cloud White accents on the sole and nubuck leather 3-Stripes. The shoe is designed with a Continental rubber outsole, which provides excellent grip and traction on both wet and dry surfaces.
We think that one of the most significant features of the adidas Ultra Boost 4.0 Tech Ink is the innovative technology used in the shoe's construction. The outer layer of the shoe is made with a PrimeKnit material that provides maximum support, breathability, and flexibility. This material is created by fusing yarn together to create a seamless upper, delivering a snug and comfortable fit for the wearer. The shoe was released on July 27th, 2018, at a retail price of $180.
