Adidas was founded by Adolf "Adi" Dassler who made sports shoes in his mother's scullery or laundry room in Herzogenaurach, Germany after his return from World War I. In July 1924, his older brother Rudolf joined the business, which became Dassler Brothers Shoe Factory (Gebrüder Dassler Schuhfabrik).
Dassler assisted in the development of spiked running shoes (spikes) for multiple athletic events. To enhance the quality of spiked athletic footwear, he transitioned from a previous model of heavy metal spikes to utilising canvas and rubber. In 1936, Dassler persuaded U.S. sprinter Jesse Owens to use his hand made spikes at the 1936 Summer Olympics.
The brothers split up in 1947 after relations between them had broken down.
In 1948, the first football match after World War II, several members of the West German national football team wore Puma boots, including the scorer of West Germany's first post-war goal, Herbert Burdenski.

In 1952, following the 1952 Summer Olympics, Adidas acquired its signature 3-stripe logo from the Finnish athletic footwear brand Karhu Sports, for two bottles of whiskey and the equivalent of 1600 euros.

In 1992, unable to pay the loan interest, Tapie mandated the Crédit Lyonnais bank to sell Adidas, and the bank subsequently converted the outstanding debt owed into equity of the enterprise, which was unusual as per the prevalent French banking practice.
