    Cariuma was founded in 2018 in Rio, Brazil, by David Python and Fernando Porto, two friends with a passion for board sports.

    The two founders saw the lack of sustainable shoes capable of living up to the demands of everyday wear and skating and wanted to transform the sneaker industry by creating sneakers that were actually comfortable and sustainable.

    Fast forward four years, the brand has remained true to its ethos of sustainable skate shoes and has released seven styles of cool sustainable sneaker retailing on its website. Cariuma ships worldwide.

    Allbirds founders

    Allbirds was launched in San Francisco in 2014 by founders Tim Brown and Joey Zwillinger.

    Native New-Zealander Tim Brown saw how versatile and sustainable New-Zealand Merino wool was and wondered why it was virtually absent in the footwear industry. So he teamed up with San Franciscan Joey, a sustainability pioneer, to create one of the world’s most sustainable sneakers.

    Eight years into the business, Allbirds have set the standard of sustainable sneakers and now have created a range of ethical shoes, sneakers, flats, and slip-on shoes for men, women, and children.

    Cariuma is a brand with roots focused on sustainability. Cariuma achieved B Corporation status in 2021, thanks to its sustainable production model, from responsible materials sourcing to ethical manufacturing and environmental protection.

    Cariuma uses sustainable materials, including organic cotton, natural rubber, cork insoles, responsibly sourced LWG leather and suede, and recycled plastic to create its signature styles. Plus, the brand uses 100% recyclable and recycled packaging to ship its shoes.

    Through the brand’s reforestation initiative, which focuses on restoring biodiversity and the carbon-capturing potential of the Brazilian rainforest, Cariuma will plant two trees for every pair of Cariuma’s purchased.

    Allbirds have focused on building a sustainable shoe brand since day one. The brand has been a Certified B Corp since 2016, meaning they balance people and the environment over profits.

    Allbirds use sustainable and natural materials, including ZQ merino-wool, sugarcane EVA, and Eucalyptus fibers, to craft their comfortable sneakers and running shoe styles.

    Plus, Allbirds works to reduce its carbon emissions by offsetting all the CO2 produced in its supply chain and shipping through carbon offset initiatives such as renewable energy and wind farm projects.

    Overall the reviews of Cariuma are incredibly positive, with over five thousand five star reviews.

    A call out that many customers point out is that Cariuma shoes are extremely comfortable, high quality, and well made. In addition, the Cariuma shoes are versatile and can be dressed up or down.

    Other reviewers also mention that for a skate-style shoe with a flat sole, Cariuma shoes offer good sole support compared to other competitors such as Converse and Vans.

    We’ve tested both the Allbirds Tree Dasher and Tree Piper and can tell you first hand that Allbirds shoes are good quality.

    ❌ While there are pros and cons to every shoe, some negative comments from customers mention Cariuma’s can cause blisters after the first few years; however, the shoes usually break in quickly after a couple of wears.

    ❌ Also, a note on the price point; Cariuma’s are slightly pricier than other skate shoes. However, the brand’s eco-friendly production practices, use of sustainable materials, and ethical manufacturing go above and beyond competitors in the market.

    ❌ One of the drawbacks of Allbirds sneakers is that not all styles are waterproof. The brand does have a water-resistant shoe with the Mizzles range, which is water-resistant; however, if you’re looking for a completely waterproof style, Allbirds doesn’t yet offer.

    Cariuma says their shoes run true to size, although the brand recommends sizing up if you’re a half size. This point is also echoed in the overall reviews of Cariuma shoes.

    Allbirds fit true to size; however, if you are in-between sizes, Allbirds recommends sizing down.

    Allbirds Tree Dasher

    ❌ No, Cariuma uses leather and suede for its leather sneaker styles, meaning the brand isn’t entirely vegan. However, Cariuma does produce vegan shoe styles, with 65% of Cariumas’s range being vegan, including the vegan suede Caturi boot, and OCA low in fabric.

    While there are pros and cons to each brand, it’s clear that both brands are creating sustainable and ethical sneakers from sustainable materials.

    Both brands are B Corporations, meaning they balance people and the planet over profits.

    If you’re looking for vegan sneakers, the Cariuma OCA or IBI styles are a good choice. 65% of Cariuma’s shoes are vegan, and currently, Allbirds doesn’t create any vegan styles.

    If you’re looking for shoes you can run in and walk long distances, we would personally recommend Allbirds Tree Dashers. The popular running shoe is suitable for mid distances and comfortable walking long distances.


    Overall, both shoes create stylish and sustainable shoes, so whichever brand you choose, you know you’re supporting a shoe brand that cares for both people and the planet.
