We replace animal hides and synthetic plastics with supple plant-based skins and work exclusively with Italian partners who share our commitment to uncompromising quality and sustainable, humane, recyclable processes. From insoles and lasts to adhesives and uppers, our shoes aren’t just vegan, they’re clean. They’re also handmade in one’s of Italy’s premier factories, with ethical working conditions, by generational artisans paid a living wage.
Our name speaks to this transparent ethos. O2 represents pure oxygen: the third most common element in the universe and a building block of life. We like to think of our shoes as building blocks of a modern, mindful wardrobe that helps you live your best life — and protects our collective future. Our limited-edition drops provide a monthly breath of fresh air (and minimize overstock).
