With 20 billion pairs of shoes produced annually, and according to the U.S. Department of the Interior, at least 300 million pairs of shoes thrown away each year- the footwear industry is one of the most wasteful. These shoes end up in landfills, where they can take 30 to 40 years to decompose. Most shoes are made from unsustainable and nonbiodegradable materials, proving the waste to be harmful to the furthest extent. Additionally, the creation process of these shoes “use virgin plastic, rubber, and petroleum, producing alarming amounts of carbon dioxide” (BUSINESS INSIDER.COM).
The problem with carbon dioxide is that it is a greenhouse gas. This means, the buildup of CO2 in the air creates a cover in the atmosphere, which traps the heat from the sunlight. This causes immediate fluctuating temperatures, and overall, a steady rise. The unnatural temperature increase plays a big role in global warming and rising sea temperatures consequently.
In order to prevent these negative results, it is important to be aware about how sustainable your preferred shoe brands are. That said, here is a compiled list of recommended, sustainable footwear brands.

This startup was founded in 2014, with a different mindset in comparison to other already-popular brands. While other brands strive to change their unsustainable materials, Nothing New’s core idea is sustainability.
