In November 2018, the Undefeated x adidas Ultra Boost made its way onto the feet of sneaker fans everywhere. Los Angeles-based sneaker boutique Undefeated skillfully lent a hand in the design of this performance pair of adidas Ultra Boosts. Set in a grayscale color palette, the running sneaker features multiple shades of the subdued tone. Undefeated branding can be found on the translucent midfoot cage, one of the tongue badges, and heel tab. The Undefeated x adidas Ultra Boost was launched as part of a massive collection that featured both footwear and apparel.
