Overview

Endless comfort, ultimate warmth. Introducing Ibira.

Built for the coldest of winter days, this boot is designed to withstand icy winds and negative temperatures. Ibira is consciously crafted with weatherproof nubuck and lined with GRS-certified shearling from toe to heel.

This style has a new tractor inspired outsole with enhanced lugs for durable traction on ice and snow. It’s made with 100% slip-resistant natural rubber for a winter boot that’s designed to take you places, no matter the conditions.

Buy 1 Pair, Plant 2 Trees.

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

Cariuma shoes are the only shoes I buy. I have a size 5 foot and they always fit perfect! So comfortable that I almost have every shoe available. Now I just need the Catiba Pro 2.0 to have more colors!!

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 two trees in the Brazilian rainforest to directly aid in the restoration and preservation of these natural habitats.
