A battle has been ongoing in a quiet town in Germany for nearly a century. This is not a war fought with guns or armies, but a feud so intense that it has divided families, neighbors, and even the streets. At the center of this conflict are two brothers, Adolf and Rudolf Dassler, whose ambitions, betrayals, and relentless competition led to the creation of two of the most powerful sports brands in the world: Adidas and Puma.

However, their legacy is not solely about sneakers and success; it also encompasses lies, sabotage, and a family torn apart forever.
A Humble Beginning Turned Bitter
Adolf, commonly known as “Adi,” and Rudolf, referred to as “Rudi,” were born in the early 1900s in Herzogenaurach, a small town with a long-standing tradition in shoemaking. Their father worked in a factory, while their mother managed a laundry business. As children, the brothers helped their mother, often running through the streets to deliver freshly cleaned clothes. However, as they grew older, their paths began to diverge. Adi, a quiet perfectionist, developed a fascination with crafting shoes, while Rudi, an outgoing businessman, had a talent for selling them.

World War I disrupted their childhood, and when they returned home, Germany lay in ruins. Determined to rebuild their future, Adi conceived a revolutionary idea: to create shoes specifically designed for athletes. He converted his mother’s laundry shed into a workshop, scavenged materials from abandoned battlefields, and began making sports shoes. Recognizing the potential, Rudi decided to join his brother. Together, they launched the Dassler Brothers Shoe Factory in 1924.
A Dangerous Gamble with History
By the 1930s, the Dassler brothers had established a reputation for themselves in the shoe industry. Their athletic footwear was popular among athletes throughout Germany. However, as Adolf Hitler rose to power, the Nazi regime began to promote physical fitness as a means to strengthen the German populace. This created a high demand for sports shoes, and the Dassler brothers were poised to take advantage of this opportunity. They officially joined the Nazi Party, a decision that would later cast a shadow over their legacy, whether motivated by necessity or ideology.

In 1936, they took their biggest gamble by sponsoring an athlete who would challenge Hitler’s racist ideology: Jesse Owens, the African-American sprinter competing in the Berlin Olympics. This was a risky move, as Hitler viewed the games as a display of Aryan superiority, and Owens’ success would be a direct blow to Nazi propaganda. Adi saw this as a unique opportunity; he gave Owens a pair of Dassler running shoes, and the athlete went on to win four gold medals. This victory significantly boosted the brand’s reputation, but tensions between the brothers were growing behind the scenes.
The Feud That Tore a Family Apart
As World War II began, the rifts in their partnership deepened. The factory, originally dedicated to producing shoes, was repurposed to manufacture weapons for the German army. Rudi was drafted into the military, while Adi stayed behind to manage the operations. Rudi suspected that his brother had arranged for him to be sent to the front lines as a way to push him out of the business. This paranoia escalated and reached a breaking point when Rudi was arrested by the Allies on suspicion of Nazi involvement. He became convinced that Adi had betrayed him.

After the war concluded, the brothers’ relationship was irreparable. In 1948, they divided the company in two Adi established Adidas, while Rudi created Puma. However, the feud did not cease; it merely intensified.
A Town Divided by Sneakers
The rivalry between the two brothers permeated every aspect of their hometown. Employees were forced to choose sides—were they loyal to Adidas or Puma? Families became divided, friends turned against each other, and even local businesses took sides with one brand or the other. Herzogenaurach earned the nickname “town of bent necks” because residents would constantly look down to check the shoes someone was wearing before deciding whether to engage in conversation with them.

As Adidas and Puma competed for market dominance, their rivalry spurred significant innovations in sports footwear. Adidas introduced the iconic three-stripe design and developed the first adjustable cleats, which contributed to the German national football team’s victory in the 1954 World Cup. In response, Puma made its own advancements, including the introduction of screw-in studs that transformed soccer footwear.
Sabotage and Revenge
The conflict between the brothers wasn’t purely about business; it was deeply personal. Puma’s shipments mysteriously disappeared at customs just before the 1956 Olympics, with rumors suggesting that Adidas had bribed officials to interfere. In response, Puma attempted to attract Adidas-sponsored athletes by offering them lucrative deals. Every success achieved by one brand was swiftly countered by the other, creating a hostile rivalry.

Even in their later years, neither brother sought to reconcile. They lived in the same town but never spoke to each other again. When they died, they were buried in the same cemetery on opposite sides.
The Legacy of a Rivalry
Today, Adidas and Puma are two of the most recognized sports brands in the world. Although the personal feud between the Dassler brothers has long since ended, their rivalry created a legacy that continues to influence the sports industry. The town of Herzogenaurach, which was once deeply divided, has gradually started to heal, though the echoes of the past still linger.

A rivalry that began with two brothers vying for control resulted in two global empires, demonstrating that sometimes the most intense conflicts occur not on battlefields, but within the confines of a family.
Was the rivalry between Adidas and Puma a necessary evil that drove innovation, or was it a tragic tale of brotherhood lost to ambition? Share your thoughts in the comments.
