The Undefeated x Neighborhood x adidas ZX 8000 ‘Black Gum’ is taken from a larger collaboration between the LA retailer and Japanese streetwear brand. The vintage runner carries a black technical mesh upper with tonal nubuck overlays and 3M reflective detailing. Mismatched Neighborhood and Undefeated branding is applied to the right and left tongue, both of which are equipped with a zippered stash pocket. Additional branding hits land on the eyestay and heel tab. The sneaker rides on a matching black EVA midsole, supported underfoot by a gum rubber outsole.
