Detailed images of the UltraBOOST 4.0 have emerged showing off the finer details of the next BOOST flagship.
They say if it ain't broke don't fix it, so this new UltraBOOST iteration is largely the same as its predecessors; only the pattern of the foot-hugging Primeknit upper has been overhauled. The ribbed look of the 3.0 has been retained, albeit executed in a completely different way. Intricate patterning has been added to the toe box, reminiscent of the 1.0. The 4.0 will also debut a new 'BOOST' logo on its inner soles.
