Vivobarefoot has obtained B Corporation certification, which is granted to businesses that “meet the highest standards of verified social and environmental performance, public transparency, and legal accountability to balance profit and purpose,” according to B Lab, a non-profit organization that manages the certification scheme.

Vivobarefoot was founded by its chief executive Galahad Clark, a sixth-generation member of the Clarks’ shoe-making dynasty. Last year, the company posted sales of £26.2 million (€28.3m-$33.5m).

The brand uses recycled plastic bottles, bio-based materials and leather sourced from independent farmers in Africa. Next year, it will be launching 3D shoe-printing for a made-to-order service that cuts waste and addresses the issue of excess inventory.

The firm also set up a re-commerce site, Revivo, that enables returned shoes to be reconditioned and sold at a lower price. Vivobarefoot’s new shoes retail around £150 a pair.
