The adidas Ultra Boost 4.0 in Triple White is finally in the Fall of 2017. This 4.0 version basically looks like a blend between the 1.0 and 3.0 editions. Featuring the signature Primeknit upper from the Ultra Boost 3.0, the current semi-translucent cage is now replaced with the original solid iteration from the classic Ultra Boost 1.0. Completing the design altogether is a matching white boost midsole and black rubber outsole.
