"The YEEZY BOOST 350 V2features an upper composed of re-engineered Primeknit. The post-dyed monofilament side stripe is woven into the upper. Reflective threads are woven into the laces. The midsole utilizes adidas' innovative BOOST™ technology.." From Adidas website. Gently used pair of Kanye West designer running shoes, sneakers luxury line. Clean, super comfortable and stylish to boot, but unfortunately, they are too small for my growing son. NO BOX. Thanks for looking and happy poshing! Cheers! XX
