The adidas Yeezy Quantum Kids ‘Barium’ makes use of a grey jacquard knit inlay reinforced with a translucent RPU cage on the side panels. A synthetic suede toe cap delivers added durability, while reflective detailing throughout the upper provides enhanced visibility in low-light conditions, including the seamless external heel counter. The midsole features a full-length Boost unit in a semi-translucent TPU cage.
