7 Sustainable Sock Brands to Help You Reduce Your Carbon Footprint


Keep your toes warm and the planet cool with these sustainable sock brands that use recycled, natural, and bio-based materials.

Dressing sustainably is a top priority for many eco-conscious consumers. For those looking to lessen their environmental footprint, start with the basics: sustainable socks.

What to do with old socks

Opting for sustainable essentials when shopping — from your underwear down to your socks — is an easy swap. Of course, that’s not to say that you should go and throw away all of your old socks in favor of new, more eco-friendly pairs. 

The number of old socks that are discarded every year may seem meager compared to garments. (About 11,300 tons of socks made their way to landfills in 2020.) But when they do reach their expiration date — mismatched, stretched out, holey, and all — make sure you discard them sustainably. 

There are a number of textile recycling programs, such as the Council for Textile Recycling, Nice Laundry, and Terracycle, that can give your old socks a new lease on life. You can also repurpose old pairs, using them as cleaning rags or dog toys.  

What about wool socks?

While wool has been a preferred sock fiber for centuries, there are reasons to reconsider using it and opt for plant-based fibers instead. Wool is an animal product, and some people choose not to use animal products due to concerns about the treatment of animals in the wool industry. These concerns may include the welfare of sheep and the practices used in shearing. There are also environmental concerns; while wool is a natural and biodegradable material, sheep have significant environmental impacts, such as land degradation and methane emissions. Methane is a greenhouse gas that traps more heat than carbon in the short term, accelerating global warming.

There are other reasons to avoid wool, too, as some people are allergic or sensitive to wool. Wearing wool socks can cause itching, redness, or other forms of skin irritation in these individuals. Wool socks also typically require more careful washing and drying than socks made from other materials. They may need to be hand-washed or washed on a gentle cycle and air-dried to prevent shrinking and maintain their shape and quality, whereas natural fibers typically don’t require such care.

Sustainable sock brands to shop

Sustainably made socks may include a number of plant-based materials including cotton or Tencel. Manufacturers are also finding ways to use upcycled plastic bottles and recycled nylon. These materials aren’t biodegradable like cotton, but they help to keep synthetic materials out of the wastestream. In some cases, these materials can be repeatedly recycled at end of life, too.
