Materials:
Kotn’s Egyptian Giza “white gold” cotton, (the main material in their ethical sustainable socks, t-shirts, and pajamas), is stronger than regular cotton and will last longer.
It’s grown in nutrient-rich soils on farms that will be 100% certified organic within the next five years.
It’s blended with 17% polyamide and 3% elastane, meaning they’re not biodegradable socks.

How We Found The Best Eco-Friendly Socks
You know when you can’t find a sock?
You sift through the laundry, look in your closet, and check under the bed.
That’s kind of what we did here—to find the brands with the best ethical socks we had to do a bit of digging.
Like some other garments, there’s a lot of intricacies knitted into warm woolies so we used our sustainable and ethical fashion guide to hunt down the most sustainable socks.
Materials:
What are eco socks made of, exactly?
We looked for brands that keep our toes toasty with some of the same fabrics that made our list of the most sustainable fabrics.
These eco-friendly materials include GOTS certified organic cotton, recycled cotton, bamboo fabric, lyocell, TENCEL™ lyocell, recycled wool, and ethical wool socks.
If looking for ethical cashmere socks, we would especially seek out recycled cashmere socks since virgin ethical cashmere is hard to achieve.
However, for those wondering “Are socks compostable?”, the answer in terms of this list is pretty much always, “NO”, because most socks (especially sustainable athletic socks) are mixed with a percentage of synthetic fabric, namely polyester, nylon, and elastane for the stretch.
In order to qualify as compostable socks, they would need to be basically plastic free socks, or contain less than 10% of synthetic fibers (the smaller the better).
When it comes to these synthetics, we looked for socks made from recycled plastic—like recycled plastic bottle socks.
Hopefully, sustainable stretch fabrics like Eco LYCRA® and Roica yarn will take the sock and sustainable activewear world by storm soon. Until then we’ll try to stick with brands that use mostly natural materials, prioritize recycled socks, and minimize elastane and spandex.
- Certifications: bluesign®, Global Organic Textile Standard (GOTS), OEKO-TEX® 100, PETA, Responsible Wool Standard (RWS), Recycled Content Standard (RCS), ZQ Merino Standard, Forestry Stewardship Council (FSC), Ecocert
Supply chain & labor practices:
We also looked at what brands are doing from a social standpoint including employing fair labor practices, ensuring safe workplaces, living wages, protection from abuse and harassment, and general employee satisfaction.
While they can’t 100% guarantee no greenwashing, third party certifications provide a little extra assurance.
- Certifications: Fair trade, World Fair Trade Organization (WTFO), Fairtrade International, ISO 14001, ISO 9001, Worldwide Responsible Accredited Production (WRAP)
Green business practices:
Brands that can prove their ethical running socks go the extra mile with practices such as carbon offsetting, plastic-free packaging, localized supply chains, take-back programs, and zero waste manufacturing, get a big thumb’s (err..toe’s?) up.
Community & charitable giving:
Do you know what keeps our toes extra toasty?
Knowing that all of the brands on this list are also brands that give back.
Whether through charity donations, environmental activism, supporting the communities that make their products, or finding a way to keep clothing out of landfills, we’re on board for any way companies positively use their profits and platforms.
Final Thoughts on Eco-Friendly Sock Brands
Clean socks, clean planet. That’s the aim of eco-friendly socks.
While they might not be the most stylish of fashion pieces, they are an essential part of any sustainable wardrobe.
Of course, you should only order a pair of these environmentally friendly socks if and when you need them.
You may have the skills to darn those holes but if you don’t, then put this list to good use and support brands trying to change the game.
Pop some affordable sustainable socks on your wish list along with a pair of ethical slippers and then have a read of our article on what to do with old socks.

Thank you for writing this article. I have been trying to find compostable socks for ages. I didn’t realize they could have Any synthetic in them so finding out that they can have a little elastane is useful info! Thanks! 🙂 Btw, Housework has some 100% compostable cotton & wool socks. Alas, they are …not in most people’s budget. But hopefully they will become so popular that the price will come down a bit. 🙂
So helpful thanks for the brand recommendation Elinor!
