The adidas Yeezy Quantum 'Onyx' is a basketball-inspired mid-top sneaker that deliver a shadowy colorway. The upper is made of mono mesh with embroidered detailing and a synthetic suede toe cap. It also has a neoprene collar for stretchy support, and reflective heel paneling for added visibility in low-light conditions. The full-length Boost midsole is enveloped in a semi-translucent TPU cage for responsive cushioning, and the herringbone-tread rubber outsole provides grippy traction.
