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.

What people are saying
INDUSTRY
Why Cariuma is the ideal partner for 4ocean
More than 24 billion pairs of shoes are produced every year, primarily under exploitative conditions, and sneaker production has become the largest and fastest-growing segment of this industry.
Sneaker production is also exceptionally carbon intensive and responsible for about 1.4% of global greenhouse gas emissions. (For comparison, air travel is responsible for around 2.5% of all emissions.) The majority of sneakers on the market today are made from petroleum-derived plastics and plastic-like materials that produce alarming amounts of carbon dioxide.
Not only are most sneakers made using virgin plastic, they’re made using a combination of different plastics that are stitched and glued together in very complicated ways, which makes them extremely difficult to recycle.
Climate change is one of the biggest threats facing our oceans and plastic contributes to climate change at every single stage of its lifecycle.
That’s why every pair of 4ocean x Cariuma Sneakers is made with a knit upper made from 100% recycled plastics. It’s also why every pair sold pulls not one but TWO POUNDS of trash from the ocean.
Our partnership with Cariuma will also help raise awareness about the ocean plastic crisis and allow more people to rep the clean ocean movement so they can start conversations that stop plastic pollution.
Our partnership also pushes back against the fast-fashion industry by showing the world that it’s not only possible to create sustainable footwear, but that it’s profitable to do so.

ABOUT
The Cariuma Story: Good things take time
After working together for a few years and bonding over their mutual love of boardsports (skateboarding, surfing & snowboarding) & their home country Brazil, co-founders Fernando Porto and David Python decided to join forces to start Cariuma. With a shared idea to build a company that would better serve people and the planet, they left their corporate footwear roles to join forces and start the sustainable sneaker company Cariuma.
They knew the industry-standard “cool-classic” sneakers were really uncomfortable and that big corporations weren’t socially responsible and didn’t really care about sustainability in an active way. David and Fernando also felt they had a duty to take a stance against the wasteful practices inherent in fast fashion, which meant it was vital for Cariuma to reinvent the sneaker game.
Being better for people and the planet has always been their first priority. From innovative designs to responsibly curated materials to shipping and everything in between, every stage of their sneaker-making process is imbued with this eco-conscious spirit.
Cariuma is now a cult favorite sustainable shoe brand that produces good-looking, crazy-comfy, and consciously-made sneakers that are designed to evolve with you and your sense of style.
