4ocean x Cariuma Ocean-Friendly Sneakers

Just in time for fall, all three of our timeless sneaker silhouettes are now available in a new black colorway. Every pair sold pulls two pounds of trash from the ocean.

Super lightweight, ultra comfy, and completely ocean friendly

4ocean is teaming up with Cariuma to stand up to the unsustainable culture of the fast fashion industry with sustainable, comfortable, and timeless sneaker designs that drive positive action for our one shared ocean.

Each pair of 4ocean x Cariuma Sneakers is made from sustainably- and responsibly-sourced materials. Use the slider to see what makes these vegan shoes so ocean friendly!

Quality over quantity

The only way to achieve authentic sustainability is by increasing the lifespan of the products we use every day so we consume less overall. That’s why longevity and mindful consumption are the name of the game for Cariuma, the cult-favorite sustainable sneaker brand that empowers conscious consumers to buy quality over quantity. Every pair of Cariuma shoes is designed to be sustainable, comfortable, and timeless.

Recycled PET Upper

4ocean x Cariuma Sneakers are the first Cariuma shoes crafted using 100% recycled plastic knit for the upper construction. This material requires minimal cutting, less labor, and less energy, which eliminates waste, reduces CO2 emissions, and creates a much more efficient sneaker design. The lining, laces, threads, and labels are also made from recycled plastic certified by the Global Recycling Standard.

Sugarcane EVA Outsole

Cariuma’s I’M GREEN-certified sugarcane is sourced from Brazil and relies on rainwater, not traditional irrigation, to thrive. It’s a fully-renewable, bio-based resource that grows quickly, naturally removes carbon from the atmosphere, and offers a softer and lighter sole than the competition. Cariuma has also perfected a unique cupsole construction and stitch method that offers extreme durability and perfect shock absorption, which significantly extends the useful life of their sneakers.

Vegan Insoles

Cariuma’s signature memory foam insole is made from cork and organic mamona oil to give you a fit that’s as comfortable as it is sustainable. The cork is carefully scraped from cork trees in a process that keeps the tree intact and allows it to grow new bark between harvests. Mamona is an organic, plant-based oil that allows Cariuma to decrease their use of virgin plastics and create much greener comfort foam.

We don’t believe in passing trends, fast fashion’s short attention span, or following the status quo. That’s why we design timeless sneaker silhouettes that are built to endure.
