Vivobarefoot designed the Ultra III using algae gathered from fresh water sources

London shoe company Vivobarefoot plans to use foam materials made by San Diego foam-to-algae production company Bloom to create the a new Ultra III running shoe product.

Bloom makes foam by locating water sources with a high risk of algae bloom, removing the excess to transform it into a flexible foam called ethylene-vinyl acetate (EVA). Vivobarefoot will have 25% of the algae-based EVA in every shoe of this design they make, potentially adding more foam in the future. The shoe company disclosed that at this ratio, a single pair returns 57 gallons of clean water to the environment and removes 40 balloons worth of carbon dioxide from the planet.

The shoes go on sale online and in stores in July 2017, priced at around $75.
