First Looks adidas Ultra BOOST 2023 When adidas debuted the next generation of Ultra BOOST models in 2019, they went big on BOOST. The next redesign, the Ultra BOOST 21, went bigger again. And you can absolutely bet your bottom dollar that the new wave of Ultra BOOST design will once again go above and beyond — but not even we thought that they’d go this big. A first look at the early sampling process of the adidas Ultra BOOST 23 shown by woganwodeyang shows a pair that goes bigger, borders, and bolder with BOOST, enlarges the OG action dots underfoot and literally shrinks everything above the high-rise sole unit. Sock uppers appear more refines, with sleeker toes and clips, and retooled caging, too.
