About the Undefeated x adidas UltraBoost 4.0 'Black'

This consortium-exclusive Undefeated x Ultra Boost 4.0 collab features a black Primeknit upper with white UNDFTD branding across the vamp, underneath the cage. The Undefeated five-strikes logo can be found on the right tongue, while an adidas logo adorns the left tongue. A white Boost midsole and white Continental rubber outsole complete the look.
