The Yeezy Quantum “Quantum” represents Kanye West’s debut sneaker in the basketball space. The shoe’s upper is strikingly similar to the Yeezy Boost 350 V2, but adds features like a heightened ankle collar, suede overlay on the toe, and ample 3M hits throughout. The grey and white tones used on both layers are complemented by reflective accents, an off-white suede toe cap and solid black hits at the collar, tongue and heel. There is also a suede overlay on the toebox, heat-sealed panels on the back, and a black slipper that extends to the ankle. Matching laces and a milky Boost sole complete this BSKTBL look.
