For as long as I can remember, I have always had a good pair of high-quality flats in my shoe collection. These are always very easy to wear with most outfits, whether we want to look more put together or casual. 

Ballet flats, loafers and mules are also effortless to slip on and off, making them the perfect shoes for our daily activities. 

However, it is nowadays difficult to find quality flats that are made to last. Those sold by fast fashion brands often wear down after a couple of months and quickly become yet another wasted pair of shoes that will sit in a landfill. Plus, they are usually produced under unethical conditions and made with unsustainable materials. 

Fortunately, some brands are making things differently. These are brands that care about their workers and how their products impact the environment. 

I have selected 12 of the most sustainable flats, loafers and mules, so you can finally get your hands, or should I say your feet, on some high-quality shoes that do not harm the planet.  


One of the most important factors to take into account when shopping for flats, loafers, or mules is that they should be durable and built to last for many years. 

Of course, make sure to pick shoes that you love, that fit you, and that are comfortable so that you will actually want to wear them. 

The brand should also be transparent about where and how the shoes are produced, and make them using sustainable materials. Workers in the supply chain should be paid a fair, living wage and work in a safe environment. 


Sustainable flats, loafers and mules are usually made from natural or recycled materials, such as recycled plastic or plant-based fibers. Some brands also use apple leather produced from discarded apple peels, which is a great vegan alternative to leather. 

If used for many years, vegetable-tanned leather sourced from tanneries certified by the Leather Working Group can also be a more eco-friendly material compared to many others. Leather is extremely durable and can last for decades if taken care of properly. 

The soles can be made from recycled rubber, recycled plastic, and even from cork, algae, sugarcane, or other plant-based materials. 


1) Margot 2.0 Square-Toe V-Cut Flats

Brand: Vivaia

Materials: Recycled Plastic, Hemp, Rubber

Price: $97-139

The Margot 2.0 flats sold by Vivaia are the perfect everyday shoes you can wear at work, to run errands, or to walk in the park. Designed in more than ten colors, they are breathable and very practical as you can put them in your washing machine when they get dirty.

They are also extremely flexible, meaning that they can easily fit in your handbag.

Vivaia’s flats are produced from six plastic water bottles that were saved from the ocean, and the slip-resistant outsole is made of natural rubber. 

The flats’ insoles contain Artemisia Argyi, a plant that helps inhibit bacterial growth and keep your feet fresh even in the heat and humidity. 

With its arch support and cushioning, walking with the Margot 2.0 feels like wearing sneakers, and its heel padding prevents you from having blisters! 

We also love that the brand ships them in packaging made of 100% recycled cardboard.
