A performance basketball sneaker envisioned by Kanye West, the adidas Yeezy Quantum 'Barium' features a opaque green Primeknit upper overlaid with semi-translucent detailing for a fluid, dynamic look. No-sew black overlays at the toe and heel provide lightweight support, while the interior bootie construction provides a snug fit. The sneaker rides on a caged Boost midsole, bolstered underfoot by a rubber outsole.
