Born from running culture, the men’s adidas Ultra Boost Uncaged shoes deliver the freedom of a cage-free design. The shoes feature an adidas Primeknit upper with integrated support to hug your foot with comfort through each phase of the gait cycle. Ultra-responsive boost absorbs the force from your footstrike to release it at push-off for a light, energised ride, while a flexible gridlike outsole stretches to adapt to the way your foot hits the ground.
