Kanye West wears a silver Yeezy 350 Boost

A few days ago, some pictures of a new colorway of the adidas Yeezy 350 Boost surfaced on the Instagram account of TeamKanyeDaily.I initially assumed that Kanye simply had the already familiar white colorway on his foot, but upon closer inspection, it looks like the upper is made of a slightly iridescent silver material.Whether the upper is still made from adidas' patented Primeknit material I honestly don't know. At least it's very hard to tell from these pictures. I mean, why not use a different material? Sure, the "Primeknit" itself is really good and in my opinion much better than the Flyknit material from Nike, but I don't think such a product diversification has ever done any sneaker any harm. What do you think? How many colorways of the Yeezy 350 Boost is this by now? All Red and All Black, Turtle Dove, All White and now Silver. Have I forgotten anything else? It's almost getting boring, don't you think? :)You can find more articles about the Yeezy 350 Boost here.
