Latest Open-source formula

Shoe startup makes its formula open-source

US shoe brand Allbirds just debuted its Sugar Zeffer flip-flops, which use the first sustainable version of EVA foam. The typical EVA foam used in shoes is produced using fossil fuels, while Allbirds’ SweetFoam is made from sugarcane. Allbirds and its partner petrochemical company Braskem has also made the formula for the material open-source, meaning that any company – in the footwear industry and beyond – has access to it. What a great way to encourage eco business activity.
