adidas’ Ultraboost’s are built with sock-like signature Primeknit uppers that adapt to every footstrike. This pair harness the power of boost™ to provide an energy-returning ride from push-off to touchdown. A midfoot cage ensures a locked-down fit and a super-grippy rubber outsole offers superior traction in both wet and dry conditions.
