The Adidas Ultra Boost is hands down the hottest sneaker of 2016 and just when you thought the three stripes was dropping fire, the uncaged version surfaces.

Seen here is the Grey/Black version featuring a black heel cup, midsole and collar perfect for the fall season. Cage or Uncaged? Let us know in the comments section what you think!
