30 years after Tretorn’s first sneaker was produced the canvas shoe had a huge breakthrough on the global market. Sneakers quickly become a global phenomenon and Tretorn became a sneakers brand on the global market. This was the prime time for Tretorn and many other sneakers brands.

During the Second World War all imports of rubber were stopped. In 1939 a nation-wide rubber collection started in Sweden. Tretorn encouraged customers to hand in old rubber boots and rubber waste and they then regenerated the rubber at the factory into new products.

October 15th, 1946 Tretorn produced a tennis ball made of dandelion rubber. The special ball was an experiment and became an innovatio

With innovations like the rubber boot, sneakers and tennis ball on the resume, Tretorn became internationally well known; with global fame Tretorn becomes Scandinavia’s biggest producer of rubber in the 1950’s. With 3000 employees Tretorn was manufacturing 7 million rubber boots a year.

After the war the farming community grew and the demand for protective footwear increased. To create protective work wear boots was in Tretorn’s DNA and we in 1952 presented the classic work wear boot Castor. It was designed with an innersole made of wood to give the rubber boot extra stability and the farmers a feeling of comfort that reminded them of wearing clogs.

Henry and Gerda Dunker started the Dunker foundation. They were committed to offer elderly care for the people living in Helsingborg and donate money to cancer research. After Henry and Gerda’s death the foundation took care of the couples house and made into a nursing home – Villa Hevea that’s still up and running to this day.

As a natural step from the success with sport shoes in the 30’s, we introduced a remake of the Tournament as an on court tennis sneaker. The style is a true original and re-launched in a contemporary eco design for 2019.

In 1955 it was time for Tretorn’s next big innovation. This was the year we invented and submitted the patent for the permanent pressurised ball or pressure less ball. The same tennis ball is used all over the world today.

Pressures less balls are designed differently from regular tennis balls in the sense that pressure less balls have bounce built into the rubber core and cannot lose pressure or bounce over time.

The only time they need replacing is when their cover becomes worn. This, on average, occurs within 1-2 years. Today, TRETORN still produce the most advanced and playable pressure less balls in the world.

In 1960 Tretorn invented low compression balls - a range of softer balls, which moved slower to enable effective and easier development of tennis skills.

First launched as “Davis Cup” and later renamed to “Racket”. This wildly popular original ‘ Racket ‘ sneaker was made for professional court tennis. With it’s robust rubber toecap and the three-layer pimpled sole, that wouldn’t wear out during the toughest of play. It was a innovative tennis clay court shoe that raised to iconic heights. This is a true original icon and re-launched in a contemporary eco design for 2019.

In 1961 Henry Dunker the founder of Tretorn dies. He leaves behind one of the largest inheritances in Sweden at that time. Since he and Gerda Dunker were childless they decided to leave in their will 58 million SEK (a value of 550 million SEK today) to the Dunker Donation Fund and the Dunker Foundation.

The money from Henry and Gerda’s Donation fund are meant to make everyday life better for the people living in Helsingborg. The money from the fund is still today distributed by Helsingborg council to build new culture and sports venues (see year 2002 for more info).

In 1967 Tretorn launched Nylite, the first luxury tennis sneaker in the world. It became a favourite when tennis stars like Björn Borg and Martina Navratilova dominated the world’s stage. Borg wore the shoe both on and off the court, and it rocketed to celebrity status after being used at both Wimbledon and US-open in the 70’s. By the late 80’s we had also established ourselves in the world of fashion. Using innovation to drive both functionality and design our shoes became style staples. The canvas Nylite was named the must-have in The Official Preppy Handbook.

Tretorn starts collaboration with Katja Of Sweden, one of Sweden’s most influential designers at the time. Katja Of Sweden was working with Tretorn, designing fashion lines, riding boots, sailing boots and sneakers for many seasons.

The Olympics took place in Mexico 1968, also known as the design Olympics because of the graphic design campaign, which became one of the most famous in Olympic history. Tretorn was proud creators of the official Swedish Olympic team sneaker and became after this event even more acknowledge as a sports and sneakers brand across the world.

In 1976 Tretorn presented a special collaboration with ABBA, designing special edition Tretorn X ABBA clogs. This was the first music collaboration in Tretorn’s history. A huge opportunity for Tretorn since ABBA was one of the world’s most famous groups at the time.

The year was 1977 and the place was Roland Garros. Guillermo Vilas was playing Brian Gottfried in the French Open final and the Tretorn tennis ball was the official match ball.

Since Tretorn sneakers had built a strong connection to the US sports market Tretorn decided to move the sports shoes manufacturing so it would be “Made in USA”.

The outdoor lifestyle grew in Sweden. People were out hiking, fishing and spending time at their summerhouses. Tretorn’s classic rubber boot Strong was presented for the first time and become popular for the whole family. Strong is still today one of Tretorn’s best-selling rubber boots.

During the 80’s the preppy trend grew in US and the famous Preppy Handbook was written. The book taught the readers where to shop, what to wear and became quickly very popular among young people. Nylite had at that time been seen on several famous people and had a celebrity status. In 1980’s when the Preppy Handbook was released, Nylite was named as one of “the must-have sneakers ” in the handbook. A huge recognition that made the shoe even more popular!

By this time Björn Borg had been working with Tretorn for many years. But in 1985 he officially joins the Tretorn Advisory team as an expert to help out with product innovation and marketing. He plays an active part in the Tretorn team, giving advice to improve existing products and ideas for new products. His analyses of product development were just as highly quality-conscious as his tennis game.

Like Tretorn Björn Borg was convinced that there are no shortcuts to success. There is no substitute for hard work. Three years after the XL Tennis Ball launch Tretorn launches the PLUS ball together with Björn Borg.

Production of the Tretorn XL and PLUS is based on unique new rubber compound. Application of these materials demanded totally new production technology. Conventional manual methods were replaced by an advanced, computerized production line in which the rubber blanks for the tennis balls were manufactured to meet the utmost criteria for precision.

Björn Borg brings new creativity to the brand and the same year as the Tretorn PLUS Ball was launched Björn Borg plays tennis with Tretorn at the Great Wall of China.
