These amazing shoes are made from organic cotton, wool, coconut husks, natural latex, cork, and leather. “All our materials come from naturally renewable sources and are responsibly harvested. They contain no pesticides, bleaches or toxic dyes and are locally sourced wherever possible. We use organic cotton in our shoes and all our leather is chromium-free. You can read about our materials in more detail here.” Every shoe has a complete materials description (click on the “materials” tab on each product page). Great styles! This company is based in the UK. I don’t usually recommend websites out of the country, but I’ve never seen anything like these shoes! You can even have them custom-make shoes to your own design specifications.
