On, a Swiss sportswear brand, has developed a hi-tech sneaker production method. Their LightSpray technique, developed at their Zurich-based On Lab, starts with a molded midsole connected to a shoe last. These are held by a robot arm while the entire rest of the shoe is basically sprayed onto the last.

“Our robot fuses 1.5km of filament in a complex pattern onto a high-performance racing midsole, forming the complete shoe upper in a single, three-minute step. No glues, no seams. Reducing waste and emissions.”

The company also makes sneakers the conventional way, and they say the LightSpray technique cuts carbon emissions by 75% compared to their standard racing shoe uppers.

LightSpray will be used to make On’s forthcoming Cloudboom Strike LS, their lightest offering, at 30g (1.1 oz).

No release date has been announced, but the shoes will reportedly retail for $330.

For comparison’s sake, see the insane amount of work that goes into making a conventional sneaker.
