The Undefeated x UltraBoost ‘Shift Grey’ subtly features a completely neutral colorway, with subdued logos that draw attention to the collaborative nature of the release. A breathable Primeknit upper, blending black and grey fibers, is reinforced by a translucent TPU cage marked by UNDFTD lettering. Different tongue tags display Undefeated’s Five Strikes on the right shoe and an adidas logo on the left.
