The Overkill x adidas ZX 8500 ‘A-ZX Series’ is a collaboration with Berlin-based retailer Overkill, and it represents the letter ‘O’ in a larger collection that celebrates adidas' iconic ZX running franchise. This vintage running shoe embraces a maximalist design inspired by the store's name, featuring a vibrant mix of colors on its mesh and suede upper. Graffiti-style branding can be seen with the 'Overkill' inscription on the lateral toe, as well as mismatched 'OK' and Trefoil tags on each tongue. For added protection, the shoes also come with a black mesh shroud to shield against any accidental paint drips.
