    • Our research and product development methods are founded on 4 guiding principles:

      - Minimize use of non-renewable petroleum-based materials.

      - Maximize use of renewable materials.

      - Provide complete information about material compositions.

      - Solve the end-of-life problem. 

      We believe in the old maxim: what gets measured, gets done. As such, we provide detailed material descriptions and meticulously measure our environmental impact (via a third-party environmental consultancy). By setting benchmarks we hold ourselves accountable and are able to continually review and improve our product. You can contact our support team 7 days a week with any questions.

    • A full material breakdown and percentages of the various components that make up our sneakers can be found in the science section of our website.

    • We look beyond manufacturing and calculate the cradle-to-cradle impact of our sneakers. 

      We take into account who our sub-suppliers are, where they're based and how far materials need to travel, as well as the usage/wear and end-of-life implications of our shoes.

      See each individual product page for detailed carbon footprint figures.

    • When we design and produce our shoes we try not to compromise, and to take responsibility for ensuring each part of the Supply Chain meets our standards. We use a mix of innovative performance materials from certified suppliers and luxurious classics to produce a lightweight yet bold product. Our sneakers are designed for versatility and are built to last.

    • Yes, we maintain records of all our suppliers’ certifications and material authentications.

      These include: LWG (Leather Working Group), GOTS Global Organic Textile Standard), BCI (Better Cotton Initiative), FSC (Forest Stewardship Council), GRS (Global Recycle Standard), ISO, TENCEL Lyocell, SEAQUAL, and ECONYL among others.

    • We use recycled leather and virgin leather as it is an organic material that is biodegradable. Vegan leather (which is typically polyurethane) is petroleum-based and we work to minimize the use of non-renewable petroleum-based products as far as material science currently allows. 

      Leather has many benefits when used for footwear:
      - It is naturally breathable and keeps feet comfortable all day. Leather shapes and stretches to conform to your feet.

      - It is highly durable; leather shoes can last for many years if they are properly cared for.
      - It is highly resistant to dirt and marks.

      - Weatherproof. When correctly treated, leather shoes can keep feet warm and dry in almost any condition.

      All leather used in Roscomar sneakers is Gold certified (the highest rating) by Leather Working Group. LWG is a global environmental stewardship protocol specifically for the leather manufacturing industry with regular supply chain audits.

    • Yes. Our Vegan Court 50/50 is made from Microfiber and ECONYL and comes in Triple Black and Triple Grey. You can find a full material breakdown here. 

    • Sugarcane is a grass (a renewable biological fiber). The Sugarcane we use comes from Brazil, where it is watered by rainfall and thereby limiting manual irrigation and using minimal fertilization. It is harvested and processed into granules that can be used like a traditional EVA material. Sugarcane reproduces in cycles of less than a year, making it an even more sustainable fiber.

      Compared to traditional EVA, which is petroleum-based, sugarcane is much better for the environment and has lower CO2 emissions. Roscomar sneakers are made with a midsole containing 69% sugarcane EVA (the highest percentage currently possible).

      Why sugarcane EVA?

      EVA is a great material to make sneaker soles. Replacing traditional petroleum-based EVA with sugarcane-based EVA does not diminish the great properties of EVA. It is soft and sturdy at the same time, giving soles a good bounce without losing rebound or elasticity. It is also super lightweight, very weatherproof, and durable.

    • Please utilize our free, simple & quick returns to send them to their Afterlife 

      We will recycle that which can be recycled, such as rubber. Natural materials such as leather, suede, and cotton, are composted or reprocessed to make new materials. We work with one of the global leaders in textile and footwear recycling who process about 35,000 pairs of shoes every day.

    • The longer you have and wear your sneakers, the more sustainable they are. By extending the life of your sneakers and avoiding replacing them, they spread out their carbon footprint over a longer period of time.

    • You can protect your sneakers with Liquiproof Labs Premium Protector.
