The adidas Yeezy Boost 380 ‘Onyx Non-Reflectiveï¿?delivers a subdued rendition of the minimalist lifestyle sneaker. A charcoal grey finish dominates the re-engineered Primeknit upper, with inky black and a subtle streak of navy blue surrounding the translucent monofilament window. The sock-like build sits atop a full-length Boost midsole, encaged in semi-translucent rubber and supported underfoot by a herringbone traction outsole.
