For this series published in WIRED magazine Alastair visited adidas' headquarters in Herzogenaurach, where new materials and concepts are tested by robots and athletes covered in sensors, and where skilled cobblers hand make prototypes of new shoes. Furthermore, he visited a factory in Indonesia where over 10,000 workers churn out 75,000 pairs of shoes per day and the Speedfactory in Bavaria where customised shoes can be produced from raw materials within a day, and which adidas sees as the future of its production.
