The Ultra Boost placed first on the Best Sneakers of 2015 list, and it doesn't look like adidas is slowing down the momentum any time soon. Detailed images of two new colorways using metallic gold and metallic silver have surfaced. With the  2016 Olympic Games taking placing in Rio de Janeiro, Brazil later this year it wouldn't come as a surprise if these two colorways were part of a "Olympic Medals" Pack.

A black and dark grey gradient Primeknit is paired with a metallic gold heel cup on pair, while the metallic silver pair incorporates a more intricate combination of black, grey, light grey and silver on the Primeknit.

There's no official information on these Ultra Boosts as of yet so stay posted for everything from a release date to a possible bronze colorway. Whether these are part of an "Olympic Medals" Pack or not, expect the metallic gold and silver Ultra Boosts to be well received.
