Facts The adidas Yeezy Quantum ‘Mono Carbon’ presents a neutral colorway of the basketball-inspired silhouette. The mixed-material upper features a stretchy neoprene collar and a jacquard mesh base, fortified with a series of wavy textile overlays in a blend of grey and off-white tones. Synthetic suede reinforces the toe, while a reflective heel counter delivers rearfoot stability. Responsive cushioning arrives via a full-length Boost midsole, enveloped in a semi-translucent TPU cage and supported by a herringbone-tread rubber outsole.
