On Running, a sportswear brand, has recently launched an automated factory in Busan, South Korea where robots are used to manufacture running shoes. The company expresses its intent to establish more such factories in the United States and Europe to accelerate its production and delivery timelines.

Embracing Nearshoring

Due to rising tariffs, supply chain disruptions, and geopolitical risks, several retailers and brands are considering ‘nearshoring’. This involves shifting the manufacturing process closer to the final consumer. On Running aims to expedite shoe production, decrease its environmental footprint, and bring manufacturing closer to its main markets by embracing automation. This approach contrasts with the traditional footwear manufacturing model, which typically involves shipping finished products from factories in Southeast Asia and China to customers in the US and Europe.

Caspar Coppetti, co-founder of On, believes that automation and nearshoring are the way forward. He cites the increasing speed to market, sustainability efforts, and the growing scarcity of regions with cheap labor as reasons to pursue this direction. At present, On sources 90% of its shoes from third-party manufacturers in Vietnam and the remaining 10% from Indonesia, as per their most recent annual report.

Automated Manufacturing Expansion

On Running first revealed its LightSpray marathon running shoe at the 2024 Paris Olympics. This innovative shoe is created by robot arms spraying material onto a mold to generate a sock-like upper. The company’s factory in Busan, equipped with 32 robots, marks a significant expansion from its initial automated factory in Zurich, which only has four robots and commenced production in July of the previous year.

This new factory can manufacture approximately 1,000 pairs of shoes daily. The spray-on method simplifies the traditional upper manufacturing process, reducing a complex 200-step procedure across multiple factories to a single automated operation.

On Running, established in Switzerland in 2010, plans to develop robot factories in the US in a bid to mitigate its tariff expenses. Steep tariffs introduced by the US on sportswear manufacturing hubs such as Vietnam and China have escalated costs and affected the industry significantly over the past year. The recent Supreme Court ruling against tariffs has added further uncertainty for retailers and importers.

Competing with Industry Giants

In the intense competition to produce the fastest marathon shoe, not just for elite athletes but also for amateur runners eager to beat their personal bests, On Running has promoted the LightSpray as a game-changer due to its light weight. Hellen Obiri, an On-sponsored athlete, wore the LightSpray when she triumphed in the New York Marathon last November.
