The Yeezy Boost 350 V2 ?Yeshaya? makes use of a re-engineered Primeknit upper that weaves in light grey fibers to contrast a neutral white base. A post-dyed monofilament side stripe adds a see-through element to the upper . while reflective threads in the rope laces add visibility in low-light conditions. The lightweight build sits atop a semi-translucent midsole housing adidas Boost cushioning.
