Known for breathability and support, the UltraBoost 19 comes in a 'Linen Green' colorway for this June 2019 rendition. Promoting premium ventilation and maximum stability, the Primeknit upper uses fused yarn to create a one-piece upper with a sock-like fit. A lace-through cage in green adds structure to the silhouette and matches the added support at the heel. adidas Boost technology supports the foot from below, utilizing energy capsules for a responsive ride.
