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.

Customer Reviews
Based on 1536 reviews87%(1332)10%(159)1%(22)1%(12)1%(11)EFit: True to sizeI really love these sneakers! For looks, I would give them 10 stars. I was nervous about how the two tones of white would look in real life, but it’s absolutely perfect. I would say that the off-white portion is really more of a pale gray/bone color. For fit, I’m going to say 4 stars… I imagine the canvas ones are a little bit more comfortable, but, the leather has very little give, so it presses on the sides of my toes a little bit more than I would like. I bought these to do all my walking in when I go to Portugal, but now I am reconsidering because of that. I might just get a canvas pair in the hopes that it they will be more comfortable.
DFit: Runs largeI printed out a return for refund label and will be boxing them up to send back.
CFit: Runs largeVery well made. I just found it to run bigger than advertised.

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.
