It all starts with design

Made from biowaste, our slippers are non-toxic, leave no microplastics, and remain fully durable in use. The material resists heat, moisture, and abrasion, while reducing reliance on fossil resources and enabling safe biodegradation at end of life.

The next generation is here

1st month of biodegradation

Biodegradation only occurs under specific environmental conditions, such as in controlled composting or the right biological ecosystem, ensuring the product remains stable and reliable during use.

3rd month of biodegradation

After around 3 months in the right biological conditions with moisture, microorganisms begin breaking down the material into natural components like biomass, water, and CO₂.

6th month of biodegradation

To comply with ISO 17556, at least 90% of the material must biodegrade within 6 months under the right biological conditions, ensuring it can break down efficiently at end of life.

Circular by Design

Cork is a naturally regenerative resource that can be recycled again and again. Primal Slippers are sourced, handcrafted, and recycled entirely in Portugal, creating a fully circular system rooted in local craftsmanship and responsibility. At the end of their life, used slippers are collected and recycled into the upcycled bottom layers of new pairs, closing the loop and turning waste into material once more.

Our Mission

The Cork Forest

By enabling this circular ecosystem, Primal helps reduce waste and carbon emissions while actively supporting the biodiversity of the Montado, one of Europe’s most valuable natural landscapes.

Beyond sustainability, cork delivers exceptional performance. It is naturally supportive, lightweight, antibacterial, moisture wicking, heat regulating, and shock absorbing. Cork also offers excellent grip on wet surfaces, making it the ideal natural alternative to single use synthetic slippers, without compromising comfort, safety, or durability.
