adidas Yeezy Boost 350 Pirate Black BB5350 Release Date 。The adidas Yeezy Boost 350 V2 ‘Onyx’ applies a stealthy palette to the lifestyle silhouette that merges Kanye West’s visionary aesthetic with adidas’ performance technology. The sneaker makes use of a one-note black Primeknit upper, secured with rope laces and equipped with a pull tab at the heel. On the lateral side, a post-dyed monofilament stripe adds a see-through element to the sock-like build. A full-length Boost midsole is surrounded by a ribbed, semi-translucent TPU cage that maintains the shoe’s monochrome design.
