New adidas Ultraboost 21 with 6% more BOOST

adidas has unveiled the ULTRABOOST 21, a fresh update of the brand’s most successful running franchise. Say hello to energy!


A team of leading adidas designers and product developers worked closely with the adidas running community and testers to create the new silhouette, which reimagines the original ULTRABOOST of 2015 as well as some elements of last year’s UB20 model.   

Aside from a new silhouette with the distinctive rear end, the core development in ULTRABOOST 21 is the redesign of the shoe’s torsion system. The new adidas LEP (‘Linear Energy Push’) provides a 15% increase in forefoot bending stiffness for a more responsive stride. This works alongside adidas’ proprietary midsole BOOST technology, which packs in 6% more BOOST through an exaggerated heel curve, for even more energy return and comfort.

Alberto Uncini Manganelli, Senior Vice President, adidas Running, said: ‘Ultraboost has consistently been a unique and sensational blend of iconic design, revolutionary innovations, unparalleled performance and unique consumer experience. It has delighted millions of worldwide users every day, winning their hearts and minds and changing the way they see and feel running.’

…our primary objective is to make each shoe better than the last…

Moritz Höllmüller, Senior Design Director Footwear, adidas Running, added: “In creating the adidas ULTRABOOST 21, we have developed our most holistic running shoe ever, that is the ultimate expression of comfort and responsiveness. The ULTRABOOST is the flagship of innovation within adidas, where our primary objective is to make each shoe better than the last. ULTRABOOST 21 takes all the aesthetic ingredients that were part of the original shoe’s DNA and fuses them with the latest technology, such as adidas LEP, to create a shoe that combines all of these great design features with incredible comfort, support and energy return.


Fans can now get their hands on the latest iteration including a fluorescent yellow and white colourway, which brings the theme of high energy to life. Further limited-edition colour drops will follow.
