What Goes into Making the "World's Best Running Shoe?"

With the Ultra Boost being called the greatest running shoe adidas has every made, we took it upon ourselves to visit our friends over in Herzogenaurach, Germany at the adidas headquarters in hopes to find out more on what goes into making the "greatest" running shoe. Finding out for ourselves how much truth there was to the claim. Joined by Adrian Leek, General Manager of running; Angus Wardlaw, director of Futures in running; and Ben Herath, Vice President of running footwear design, we quickly learned that there were many parts in making the Ultra Boost a reality. From using technologies found in the aeronautical industry, the anatomical study of foot shapes, down to testing in the Black Forest with a kooky Germany family that's infatuated with running -- racking up 1000 kms of run time a week. Offering 20% more boost response than previous iterations, the Ultra Boost has a variable zone Primeknit upper joined with a newly developed TORSION system and Stretch Web outsole.
