Adding to the flames of one of the most hyped silhouettes of the year, Kanye West was spotted rocking a pair of a never before seen colorway of his signature adidas Yeezy Boost 350.

At this point, we can only speculate that this could be a future colorway or it could just as easily be an exclusive for Kanye. We'll just have to wait and see. Stay tuned as this story develops.
