The adidas UltraBoost 4.0 “Triple Black Nubuck Cage” is a premium edition of the popular all-black running shoe. The high performance runner once again goes for the “Triple Black” color scheme, but this time gets upgraded with a nubuck leather cage to complement a black Primeknit upper that is speckled with dark grey thread. Other details include a textured matte finish on the heel counter, and a small hit of dark red on the Torsion bar seen within the sole. The adidas UltraBoost 4.0 “Triple Black Nubuck Cage” released in December 2018.
