Materials startup Novoloop brings its upcycled outsole to On’s new running shoe

Making sneakers is a dirty business; one that’s heavily reliant on fossil fuels. Shoe companies have experimented with various ways to reduce their footprints, from uppers made of recycled plastic to midsoles made of foam derived from sugarcane.

Now, there’s a new approach — upcycling. Materials startup Novoloop and running-shoe manufacturer On will announce a partnership later today to produce an outsole made with upcycled thermoplastic polyurethane. It’s one of a host of materials that are debuting with On’s new climate-friendly sneaker, the Cloudprime.

The partnership will be announced at an Elemental Excelerator event later today as part of Climate Week in New York City, and TechCrunch has exclusive details about the collaboration, Novoloop’s novel material and how it’s made.
