Our mission is to help restore the biodiversity and carbon-capturing potential of rainforests.
Since June 2020, we’ve committed to planting two trees for every pair of sneakers we sell. Our work starts in the Brazilian rainforest, where only 12.4% of the forest floor remains following widespread urbanization and agricultural logging. With the goal of restoring biological diversity in this essential biome, we plant over 120 tree species, based on what’s native to each site.

Based on 219 reviews90%(198)5%(11)2%(5)1%(3)1%(2)CFit: True to sizeMost comfortable wearing slip on that performs like a walking tennis shoe.
JFit: True to sizeThis is my second pair of Cariuma slip ons (I already have these in black). They are my go-to sneaker. I hate wearing socks and these are comfortable without and don't get smelly. The slide on easily, they hold their shape and color and my only complaint would be that I want more of a color selection - I would buy them to go with every outfit.
AFit: True to sizeLove these!! True to size! Comfortable right out of the box. Get tons of compliments on them. People always ask me where I got them.
Durable and washes amazingly! You are missing out if don’t own a pair!

Get a Pair of Sneakers, Plant 2 Trees
Nurturing the planet is a cause that’s very dear to us at Cariuma. That’s why we decided to start our own Reforestation Program in our founders’ homeland, Brazil, where the rainforests are home to an increasing number of endangered plants & animals. For every pair of sustainable sneakers purchased, we plant a pair of trees in the Brazilian rainforest to directly aid in the restoration and preservation of these natural habitats.
