adidas continues to experiment with colored BOOST midsoles, following up red, orange, and black versions of its proprietary cushioning with yet another non-white introduction. This time around the Three Stripes is going with metallic silver, applying the look to a predominately grey iteration of the UltraBOOST Uncaged. As for the shoe itself, grey and black take care of the usual Primeknit upper while a black Continental rubber outsole appears below. Finally, a black heel counter provides the finishing touches.
Expect these to land soon at adi spots worldwide.
