Yeezy Boost 350 V2 ‘Sulfur’ utilizes a breathable Primeknit upper in a yellowish tan hue, accented with the sneaker’s signature monofilament side stripe in olive green. A pull tab at the heel complements the sock-like collar to deliver easy on and off. Underneath the foot, a full-length Boost unit provides responsive cushioning. The foam compound is visible through cut-out detailing on the gum rubber outsole.
