The adidas Yeezy Boost 350 V2 Core Black Red 2017 I was part of the Yeezy and adidas collaborative collection. The sneaker has an all-black colorway throughout the lace-up, and a black Primeknit upper with a stitched red SPLY-350 logo on the medial quarter panel and center seam. The crimson stitched pattern is also displayed on the pull tab at the heel. The structure is supported by a full-length boost midsole that is covered in semi-transparent chunky black rubber with a vertical linear pattern. The adidas Yeezy Boost 350 V2 Core Black Red 2017 I debuted on February 11th, 2017 and retailed at $140.
