When you wear a Cariuma IBI, you’ll be lighter on your feet and leave behind a smaller footprint.

One of the lowest carbon footprint sneakers ever made

The only true way to achieve authentic sustainability is by increasing the lifespan of the products we use every day. That’s why longevity and mindful consumption are the name of the game for Cariuma, a 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 IBI Low Tops and Slip Ons are the first Cariuma shoes crafted using fully 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 extends the useful life of their sneakers by offering extreme durability and perfect shock absorption.

Vegan Insoles

Cariuma’s signature memory foam insole uses cork and organic mamona oil for 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 a plant-based and organic oil that allows Cariuma to decrease their use of virgin plastics for a 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.

Love, love, love! Such comfortable shoes -- they’re soft and stretchy, yet provide great support. I walked 5 miles in them the first wear with no discomfort at all! And the eco-benefits of the shoes are even better!
Stands apart from other shoes first in its comforting caress, so SEAMLESSLY wrapping my feet in a breathable mesh, composed of recycled material. My feet are happy to slip into the cork insoles, which add a layer of comfort while walking.
