Thanks to the Yeezy Mafia, we're learning that this upcoming makeup will incorporate a dark brown hue on the Primeknit upper that's offset by a black semi-translucent stripe running across the lateral side. Dark brown continues onto the Boost-cushioned midsole, which sits atop a gum outsole. Note that the pair pictured above is a mock-up image of what's expected to release.
The "Cinder" makeup is rumored to be one of four pairs of the Yeezy Boost 350 V2 releasing in spring including the "Flax," "Marsh," and the "Sulfur" colorways that have yet to be revealed.
The Adidas Yeezy Boost 350 "Cinder" is expected to drop sometime in spring for $220.
