The nineteenth-year version was a genuine rebuild rather than an annual update. adidas took the original UltraBoost apart (seventeen separate components) and reassembled it around four: the Boost midsole, a torsion plate, a knitted upper and a reduced heel frame. Boost volume went up by about a fifth against the first-generation shoe. The knit was reworked as a tube that extends past the midsole edge and wraps the foot like a sock, and the plastic heel cage that had defined the model's look since 2015 was cut back to a thinner frame. The company said thousands of runners were involved in the testing. What came out was a shoe reviewers found comfortable and springy but not quick, which is roughly where the line had always sat despite being marketed as a performance runner. This colourway pairs a linen upper with black through the cage and a brown-toned sole, released toward the end of 2019.
