Adidas unveiled two new additions to the UltraBOOST range this week: the UltraBOOST All Terrain and UltraBOOST X All Terrain.

Each shoe features Adidas’ BOOSTTM technology, alongside the Continental Stretchweb outsole, splash-repellent adidas Primeknit and reflective elements to support runners in all weather conditions.

Furthermore, the UltraBOOST All Terrainincludes an integrated cage for better support, while the UltraBOOST X All Terrain, designed specifically for the female foot, includes the pioneering adaptive arch to ensure a better fit.

“The autumnal weather can be unpredictable and as a result it took us longer than usual to develop these products,” said Stephan Schneider of adidas Running. “Extensive testing ensured that each design element offers protection and uncompromised comfort in any condition. We specifically focused on increasing the ankle height in order to protect and create a smoother movement from the leg into the foot with each stride.”

The Adidas UltraBOOST All Terrain and UltraBOOST X All Terrain drop September 21 in six colorways for men (dark burgundy, grey, core black, black, khaki and green night) and two colorways for women (mystery ruby and core black) at and retailers nationwide.
