In a groundbreaking move that promises to redefine the future of running footwear, Swiss sportswear brand On has introduced its latest innovation: the Cloudboom Strike LS. Known for their revolutionary CloudTec sole, On is once again set to disrupt the market with this state-of-the-art spray-on running shoe. In a captivating video, the entire process of creating the Cloudboom Strike LS unfolds in just three minutes. From a single 1.5 km thread, a robot weaves the upper and seamlessly attaches it to the midsole—no glues, no seams.
The Birth of a Revolution
The Cloudboom Strike LS, where LS stands for LightSpray, showcases cutting-edge technology and meticulous design. Crafted from a single semi-translucent synthetic monofilament nearly a mile long, the shoe is extruded by a robot arm and engineered to perfectly fit the feet of elite runner Hellen Obiri. This unique process ensures optimal running efficiency, with the upper heat-fused to a foam rubber and carbon-fiber sole, resulting in an ultra-lightweight shoe weighing just 170 grams (about six ounces).
Eco-Friendly Engineering
Beyond its innovative design, the Cloudboom Strike LS represents a significant step forward in sustainable footwear. On reports that the shoe has 75 percent less environmental impact than traditional sneakers. With only seven components compared to the usual 150 to 200, the shoe is manufactured with precision and minimal human intervention. Parametric design principles and computational engineering replace traditional pattern-making, reducing the need for manual labor and factory assembly lines.
A Leap in Manufacturing
The production of the Cloudboom Strike LS takes place in new “production cells” located in Zurich and other key markets, rather than outsourced factories in Asia. This localized manufacturing approach drastically shortens the time between production and delivery. Remarkably, the Cloudboom Strike LS can transition from midsole to finished product in just three minutes. This efficiency eliminates waste and reduces carbon emissions by avoiding unnecessary transportation and leftover materials.
Sustainable to the Core
In a bid to further enhance sustainability, the Cloudboom Strike LS features color added via inkjet rather than traditional fabric dyeing methods. The thermoplastic filament used for the upper can be melted down and reused at the end of the shoe’s life cycle, ensuring a cradle-to-cradle design. This forward-thinking approach minimizes environmental impact and reduces stock left at the end of each season, as production can be closely matched to demand.
The Future of Footwear
On’s creation of the Cloudboom Strike LS involved building custom machines to weave the filament according to the biomechanics of the foot. This high-stakes investment in both technology and philosophy underscores On’s commitment to pushing the boundaries of what’s possible in running footwear. The result is a shoe that offers unparalleled support, breathability, and performance, all while prioritizing environmental sustainability.
The unveiling of the Cloudboom Strike LS marks a significant milestone in the evolution of running shoes. With its revolutionary design, eco-friendly production, and advanced engineering, On has set a new standard for performance and sustainability in sportswear. The Cloudboom Strike LS is not just a shoe; it’s a glimpse into the future of footwear. Prepare to be amazed and inspired as you lace up the Cloudboom Strike LS and experience the next generation of running technology.
