The adidas Yeezy Quantum Frozen Blue applies a burst of color to basketball-inspired mid-top. The layered upper features a bright blue RPU cage atop a jacquard knit upper, reinforced with synthetic suede at the toe cap. Black neoprene on the collar and tongue offers stretchy comfort, while a seamless heel counter is good for improved stability. Lightweight cushioning arrives via a Boost midsole reinforced with a semi-translucent Thermoplastic Polyurethane cage and a herringbone traction outsole underfoot.
