A New Standard In Sustainability

Erem believes that outdoor gear should not harm the outdoors, so we insist on a Biocircular™ standard for every product we sell. This means that we make our products using only materials with proven paths back to nature and that we provide each Erem product a seamless and responsible next life.

Returns To Nature


Reboot™ and Reuse

Carbon Neutral

To achieve CarbonNeutral® certification, Erem is working with the leading experts on carbon neutrality and climate finance, Natural Capital Partners.

Supporting The Desert

Erem has committed to supporting desert non-profits each year by donating 1% of our sales. Erem is a member of 1% For The Planet®.

3rd Party Verified

Erem partners with expert 3rd parties to help us audit and verify that we are achieving each of the goals we set for ourselves.


You don’t buy food containing ingredients you can’t pronounce or that you don’t recognize. Why should your gear be any different? Erem uses a small suite of versatile and trusted materials that meet our performance and environmental standards and we tell you what they are.

We will gladly share our supplier information with any company interested in improving its sustainability practices. We’re all in this together. Contact us.


Full-grain leather is a highly durable material that reduces impact by remaining useful longer in extreme desert conditions. Erem's leather is tanned with plant-based, food-grade formulations that are grown, harvested, and processed sustainably.

The Xerocole collection uses reverse grain in order to utilize leather with aesthetic marks like tick bites or scratches that, while functionally perfect, would normally be discarded.

Erem has partnered with the Savory Institute to source our leather from regenerative farms that improve soil health and sequester carbon. Learn more about the Savory Institute.


TENCEL™ Lyocell fibers come from sustainably managed forests. More than 99% of the harvested material meets FSC® and PEFC™ standards and comes from trees that don’t require pesticides, fertilizers or irrigation.

TENCEL™ has a closed-loop production process, meaning >99.5% of the used solvent is recycled and pushed back into the system instead of being flushed out as wastewater. No environmentally harmful substances are used to process wood into fiber.  The resulting fiber is certified as compostable and biodegradable under industrial, home, soil and marine conditions.


Xerocole collection soles contain 70% recycled rubber and a proprietary, added biodegradability accelerator that enables biodegradation in 7 years or less (results come from independent, 3rd party testing). By contrast, most shoes today use EVA and rubber that will take hundreds of years or more to degrade, if they ever do.

Reuse is the most sustainable option, so we work with a partner that can devulcanize our rubber soles, allowing them to be easily turned into new biodegradable rubber products, including new Erem gear.


Brass is an alloy made of zinc and copper. We use brass because of its desert-level durability and its ability to be infinitely recycled without losing its incredible performance properties. Most performance footwear hardware today uses plastic.


Cork is a highly sustainable, natural material, harvested from the cork oak which is native to the semi-desert environments of southwest Europe and northwest Africa. Cork trees are unharmed in commercial harvesting.

Even better, the raw material used in Erem’s insoles comes from the production waste of cork stoppers, disks, and other products. Our supplier transforms this cork “waste” into cork granules that can be used for shoe components. At the end of its life, cork will safely return to the Earth.


Linen comes from the flax plant—a fast-growing renewable resource that requires few, if any, chemical pesticides and fertilizers during cultivation. Flax also requires little to no irrigation and is often watered through rainfall alone.

Because of its remarkable strength, linen was the preferred thread in quality footwear for both uppers and soles, including Goodyear welting, until the rise of the cheap and ubiquitous plastics used today.

All Other Materials

The final components of the Xerocole were similarly sourced to meet our rigorous environmental standards. The Strobel sock is made from cotton, Tencel, and industrial compostable corn-based PLA. The shank board is simply recycled wood fibers, water, and calcium carbonate. Finally, our adhesive is a novel and eco-friendly compound from the skincare industry that fully breaks down with prolonged exposure to water.
