According to py_rates, a Bape x Adidas Ultra Boost will release in 2019. While details are slim, a mock-up was provided which depicts the Ultra Boost's Primeknit upper covered in camouflage. A tan support cage is contrasted with white Three Stripes branding, and the heel cup is filled with an olive shade.
Meanwhile, Yeezy Mafia has shared a second mock-up with some noticeably different details including black Boost and caging. It's currently unclear if both looks will be releasing.
