A catastrophic feud in 1948, however, led the Dassler brothers — Adi and Rudi — to split the factory in two and set up rival companies on opposite sides of town. Their unlikely story is told in this three-part series, with input from surviving members of the Dassler family, current employees, industry experts, and some of the big names in sport who have been sponsored by the brands, such as the Adidas ambassador David Beckham and the Puma representative Usain Bolt. At the heart of the book of Ruth is the promise of redemption through trusting in God: a story of love and new life triumphing over the hopelessness of grief and despair.
