PRIMAL Soles is a Dutch circular-footwear company founded by brothers David and Jeremy Even. The brand develops cork-based insoles and footwear around regenerative materials and closed-loop recycling.

PRIMAL products are made in Portugal. Its insoles combine natural cork with cushioning layers that include recycled cork and foam, while The Fløps use a bio-based cork-polymer compound for durable, washable slippers and flip-flops.

Circularity is built into the product system. PRIMAL works with Portuguese manufacturing partners to recover used cork products and return materials to production, while newer products use simplified constructions intended to support end-of-life recycling.

PRIMAL is a certified B Corporation and uses FSC-certified cork sourcing.
