This adidas Ultra Boost is a mixture between the 1.0 and 3.0 versions. Featuring a Primeknit upper from the Ultra Boost 3.0, the shoe replaces the semi-translucent cage with its original solid color from the popular Ultra Boost 1.0. Finishing off the design is a Black rubber outsole. These running shoes combine comfort and high-performance technology for a best-ever-run feeling. They have a stretchy knit upper that adapts to the changing shape of your foot as you run. Responsive midsole cushioning and a flexible outsole deliver a smooth and energised ride.
