Every year, billions of synthetic shoe insoles end up in landfills. David and Jeremy want to change that. They have created circular cork shoe insoles; a comfort product that is landfill-diverting, biodiversity-uplifting, CO2-negative and infinitely recyclable. They know that, at the scale of the footwear industry, their impact is a drop in the ocean. Still, they want to show the industry that a different approach is possible: one where nature conservation, biodiversity uplift, and profit go hand in hand.
