Adidas’ new Ultra BOOST 3.0 is back in another new colorway, dubbed “Mystery Grey”.

The BOOST midsole remains white as usual, while the Primeknit upper is done in this gray colorway, as well as the Three Stripes cage, inner lining and laces. Black is applied to the heel cup and outsole to complete the look.

This “Mystery Grey” Ultra Boost 3.0 is expected to drop Spring 2017. Stay tuned for a release date.
