On claims spray-on uppers are revolutionary
 Sportswear brand On has introduced a footwear upper technology that sprays a recyclable material in a single step using a robotic arm, in a novel process the Swiss brand claims is “revolutionary”.

LightSpray has been developed at On’s labs in Zurich and will make its first appearance in the Cloudboom Strike LS (LightSpray) high-performance running shoe.

The fully automated process reduces waste and produces an upper with 75% fewer carbon emissions than On's other racing shoes, offering the potential to make shoes closer to the customer. 

A patent-pending thermal fusing technology allows LightSpray uppers to bond to the midsole without the need for glue, and the ultra-thin and seamless design eliminates the need for laces.

Marc Maurer, co-CEO of On, said: “LightSpray marks a significant milestone for On, not only in creating high-performance products but also the potential it has to move us towards a more sustainable, circular future. Our team is constantly challenging itself to rethink the status quo in terms of the design, development and manufacturing of performance sportswear.”

The LightSpray technology has the potential to revolutionise not just footwear but other wearable products in the sportswear industry, added the company.

Earlier this year, Hellen Obiri, 4x World Champion runner and winner of the marathons in Boston and New York City, wore a development version of the Cloudboom Strike LS when she won the marathon in Boston.
