Some would say the Adidas Yeezy Boost 350 in Pirate Black is the most popular colorway of the most preferred silhouette from Kanye West's collaboration with Adidas. Released on August 22, 2015, this version of the Yeezy Boost 350 is noted for its textured black look and red accents on the heel tab. The sneaker is constructed with a woven Primeknit upper that rests atop of a TPU sole, which covers full-length Boost foam cushioning.
