Our Materials:

We work with four core materials, each carefully selected for their natural properties, durability, and responsible sourcing.

Cork: Natural. Lightweight. Regenerative.

The cork oak forest in Portugal is part of one of the world’s 36 biodiversity hotspots, has a recognized protection status, contributes to climate regulation, is a driving force for sustainable development and plays a crucial role in the world's ecological balance.
Our supply chain is also FSC certified. The mark of responsible forestry.

• Lightweight and flexible
• Hypoallergenic and odour resistant
• Fully recyclable and biodegradable
• Certification: FSC Certified

Crepe: Raw. Natural. Unprocessed.

The raw, natural rubber latex is obtained from the Hevea Brasiliensis tree. The sap is collected by cutting thin strips of bark from the tree and allowing the latex substance to be tapped. This harvesting does not weaken the tree, far from it, it actually helps it flourish. 

• 100% natural and biodegradable
• Flexible and durable
• Free from synthetic additives

Leather: Natural. Durable. Long term.

Leather shoes are more eco-friendly than any other type of shoes because it is not made from any harmful synthetic material.
Leather is made from natural resources - the skin of different animals. When your shoes get damaged, the leather will easily degrade. There are many shoe products that are made of synthetic materials and harmful to the environment. Leather makes shoes more durable which makes them a better, long-term investment. As leather is a natural material, no harmful chemicals were used to create it - making it eco-friendly!

We source leather exclusively from Leather Working Group Gold Rated suppliers, the highest global standard for environmental performance.
