  • Our heritage

    Tretorn was founded in Helsingborg, Sweden in 1891, and has come a long way since. Today, you can find our brand in stores all over the world, but we remain committed to our living heritage. For us, this means proven expertise in creating products that can withstand Scandinavian weather without getting in the way of everyday life. It also means creating products that are stylish and worn equally by city-dwellers and nature-lovers. Ultimately, Tretorn is about celebrating both style and practicality.

    In 1896, five years after the start we produced 1 million pairs of galoshes in Helsingborg and in 1900, we produced our first sneakers. Looking back we have pioneered the sneaker, the rubber boot and even the tennis ball for more than 120 years. We’ve been synonymous with the sport for the century. From our first rubber boots to the world’s first luxurious tennis sneakers.

    We’re proud of our history and our legacy. From the rough weather that got us started in 1891 to the continued improvement and innovation that keeps us going, are we celebrating our living heritage. To our first 128 years – and evolving for many more years to come.



1891 – Born Out Of Scandinavian Weather

January 3rd, 1891 the Dunker family opened up the doors to the new rubber factory that came to be known as Tretorn. The number of employees was 52 and the factory floor about 2,500 square meters. The factory produced galoshes for farmers to protect their feet. The tough Scandinavian weather was challenging for the farmers who didn’t have shoes to protect them from the cold or wet weather. The new Tretorn galoshes were a big innovation, which helped farmers all over the country to stay warm and dry when they were walking the fields. In the next coming year Tretorn produced 39 000 pair of galoshes.

1896 – 1 million galoshes

Tretorn’s innovative galoshes in combination with the tough Scandinavian weather, made the business expand swiftly. In only five years’ time Tretorn had reached a production of 1 million galoshes.

1900 – From 52 to 575

As the production increased, Tretorn expanded rapidly and only 9 years after the start increased the number of employees from 52 to 575.

1900 – First sneaker

What many don’t know is that Tretorn is the second oldest sneaker manufacture in the world. Right after the US rubber company started producing Keds. The Dunker family were big sports enthusiasts and with the knowledge how to vulcanizing rubber Henry Dunker decided to start going into the sports business. 1st May 1900, we produced our first rubber sole sneaker. A huge innovation in footwear and the beginning of a new era for Tretorn.

1902 – First tennis ball

The Dunker family took their interest in sports to next level. Two years after the first sneakers launched, Henry Dunker and Tretorn first started making tennis balls. The tennis balls became very popular and were widely distributed.

1903 – First rubber boot

Tretorn went from only producing protective galoshes for the farmers to produce the first rubber boot, as we know it today. This was a natural progression and made the rubber boot user-friendly to not only the farmers but also to regular customers.

1911 – First private day-care

The majority of the factory’s employees were women. So in 1911 Henry Dunker started one of the world’s first private day-care and called it “Barnkrubban”. They took care of the employee’s children whilst they were working. This set the standard on how the relationship and responsibility was developed between the employees and employer. Some say that “Barnkrubban” is the reason for the saying “CSR The Swedish Way”.

1915 - Appointed by the Swedish Royal Court

In 1915 Tretorn was appointed by the Swedish Royal Court by king Gustav V. Gustav V was a huge sports and hunting enthusiast and a famous tennis player under the pseudonym Mr. G. in Sweden known as V Gurra. Tretorn are still today supplying the Royal Court.

1930 – Leading on canvas shoes

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.

1939 – Regenerated rubber

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.

1946 – Dandelion tennis ball

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

50's – 7 million boots a year

1952 – Castor launch

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.

1953 – Dunker Foundation

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.

1955 - Tournament

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.

1955 – Inventing the permanent pressurised tennis ball

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.

1960 Low compression balls

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

1961 Introducing the Racket shoe

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.

1962 – Henry Dunker dies

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) .
