Want to be sustainable from head to toe? We’ve got some essentials that will knock your current (un)sustainable socks right off.
What used to be a boring yet eco-friendly Christmas gift from Grandma has come to be something many of us appreciate. Whether hiking, running, snowboarding, or simply snuggling up next to a fire with a good book, a comfy pair of eco-friendly socks goes a long way. And they should go a long way…without getting holey and leaving a footprint on our planet, that is.
If you’re wondering where to buy ethical socks, you’ve come to the right place. We considered fabrics, supply chain ethics, and various green business practices when choosing the best brands for a sock drawer refresh.
Note: Our Brand Rating System adds a few more layers to our consideration set (for rated brands who opt in), covering 22 different criteria from climate action to packaging and waste.

My Personal Review Of Paka’s Crew Socks
“I haven’t taken these socks on a hike yet but I can confirm they are super soft, very warm and comfortable and they don’t smell. Ultra-lite, these socks are ideal for almost any use and I can’t wait to try them out on the trails. They fit true to size and don’t dig in or ride down.”

My Personal Review of Conscious Steps’ Ankle Socks:
“My Millennial is showing here, but I love ankle socks, and I stand by that—at least, well-made ankle socks that don’t slip off the heels. And Conscious Steps do just that. They stay in place perfectly, are super soft, and feature extra back padding at the top, which is a small but brilliant detail, offering extra comfort and protection during long walks or workouts. While I love all my Conscious Step socks, I’m especially fond of the bright orange socks that stop violence against women. Not only do they allow me to (literally) stand for something I believe in, but the extra cushioned bottoms are just oh-so-comfortable.”

Harvest And Mill
Price Range: $20—$104 (6-pack)
If you’re looking for durable socks made in America, wander into the fields of Harvest & Mill. This all-American sustainable basics brand specializes in only the most simple and essential of wardrobe pieces. Nothing represents that so much as their crew and ankle socks in simple, earthy colors.
They’re made of a thick and cozy blend of 88% organic cotton, 10% stretch nylon, and 2% elastic. The simple colors are actually not the result of dyes, but rather the natural colors of the cotton used. They don’t process their fabrics with synthetic chemical finishes, bleach, or toxic dyes.
Harvest & Mill is our go-to source for American-made women’s clothing. Because literally every step of their supply chain is USA-based—organic cotton farming, milling, and sewing. Instead of contracting out to large companies, they partner with only small, ethical, and independent suppliers and factories.
Like their cotton and products, their biodegradable mailers are USA-made, too. By investing in renewable energy and reforestation, Harvest & Mill fully offsets the carbon footprint of their operations. They also minimize waste by using precision patterns and upcycling scraps.
My Personal Review of Harvest & Mill’s Organic Cotton Crew Socks:
“I adore the thick, slouchy feel of these highly comfy socks. They’re my go-to grab when I’m lounging about or throwing on winter boots, though I do find them a little too thick and bunchy to wear with more tight-fit shoes or for highly active purposes.”

Happy Earth
Price Range: $15—$45 (3-pack)
Happy Earth’s answer to a happy earth is organic cotton and recycled synthetics. It’s what they use across their whole range of organic sweatpants, t-shirts, hoodies, and more. Their dreamy collection of printed sustainable socks is no exception.
These organic and recycled socks feature a blend of 75% organic cotton, 23% recycled nylon, and just 2% elastane. Those gorgeous designs are the product of sustainable dyes compliant with the ZDHC Manufacturing Restricted Substances List.
Fair Trade and/or WRAP-certified factories are responsible for 95% of Happy Earth’s apparel and accessories, all of which uphold their ILO-compliant Code of Conduct. Carbon Neutral Certified, Happy Earth powers manufacturing partially with solar energy, uses sea freight shipping, and ships using lightweight 100% post consumer recycled packaging.
A member of 1% of the Planet, purchases with Happy Earth let you either plant five trees, clean one pound of trash, or fight climate change by offsetting 150 pounts of emissions. The best part is that you get to choose which at checkout!
My Personal Review of Happy Earth’s Peak Experience Socks:
“As someone who truly loves the mountains, I couldn’t resist trying the Peak Experience Socks. With their vibrant, retro hues and charming geometric mountain pattern, wearing them always brings me a little closer to my favorite peaks. Beyond the fun design, these socks are incredibly comfortable, with top-notch stitching and materials. After testing them on several long hikes, I’m happy to report they kept me blister-free!”

Allbirds
Price Range: $14—$18
Hailing from San Francisco, Allbirds is known around the globe for its sneakers. To pair with its sustainable running shoes, you’ll find plenty of sustainable running socks, as well as crew socks, hiking socks, ankle socks, and no show socks, all carefully designed to meet different performance needs.
The ethically made socks are made using a variety of different eco and recycled materials like TENCEL™, cruelty-free wool, recycled nylon, recycled polyester, plus smaller amounts of virgin polyester, nylon, and spandex. Their proprietary Trino™ (tree + Merino) yarn is soft, breathable, and moisture wicking—making it an ideal material for eco-friendly compression socks. It’s created from FSC-certified eucalyptus tree fibers combined with ZQ Merino wool.
Allbirds provides detailed information about its eco-friendly materials, like where the merino wool is sourced (New Zealand), where it’s spun (Italy), and where the eucalyptus wood comes from (South Africa). Final assembly happens in WRAP-certified factories in China and/or South Korea.
Allbirds is Carbon Neutral Certified. Each product has a carbon footprint calculator and the numbers are getting smaller all the time. 90% of their packaging is made from recycled materials.
My Personal Review of Allbirds Anytime No Show Sock:
“The Anytime No Show Sock is hands (er, feet?) down my favorite no-show sock ever. Unlike so many others I’ve tried, it actually stays put except for when in extreme motion. For example, I don’t go running in these socks, but for just about anything else, they stay put all day long.”

Patagonia
Price Range: $25—$40
Sustainable fashion old-timer Patagonia has been operating consciously—even before it was cool. Now, they combine sports, stories, and activism with their long-lasting sustainable t-shirts, leggings, and so much more. While they do have a selection of crew and quarter ethical socks that are ideal for daily wear, Patagonia is all about sustainable high quality socks for the outdoors, from ethical trainer socks to sustainable ski socks.
Eco-friendly materials used for the socks include responsibly sourced merino wool, 100% of which is RWS-certified. It’s blended with nylon, most of which now comes from recycled sources. All of the dyes are PVC-free and phthalate-free.
Patagonia works with Fair Trade certified factories for most of their goods, including an American-owned one for their made-in-the-USA sustainable wool socks The Footprint Chronicles on the bottom of each product page show what factory and what country each item was made in.
They also offer a buyback and resale program (Worn Wear Initiative), and offer lifetime repairs. Patagonia is a founding member of 1% for the Planet and has taken corporate responsibility to a new level, working to spread awareness about environmental and social issues and getting people involved through their Patagonia Action Works program. Since selling the company to two environmental nonprofits, “Earth is [Patagonia’s] only shareholder”.
Kotn
Price Range: $12—$16
Kotn is a Canadian brand which works directly with cotton farming families in Egypt, specializing in a farm-to-table-esque system that directly supports the farmers and provides customers with long-lasting wardrobe staples. As for your feet, Kotn keeps it basic with dress, and crew socks. Check them out if you’re looking for sustainable socks in Canada.
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 blended with small amounts of polyamide, polyester, and elastane
Using direct trade practices (like those in the coffee and tea industries), this Certified B Corp is able to directly support family-run farms and keep their prices stable and much higher than the average. They carry out regular audits to ensure fair working conditions are maintained, provide farming subsidies, and practice equal opportunity employment.
Kotn’s Giza cotton is the rarest type of Egyptian cotton. It only grows on a 100km stretch of land in Egypt’s Nile Delta. Since they manufacture nearby, the whole supply chain is super local. Kotn also handpicks their cotton, which preserves the integrity of the fibers, creates fewer emissions, and provides more jobs.
Partnering with a local Egyptian non-profit, Kotn helps prevent child labor by donating a portion of its proceeds to help fund and build primary schools.
Cariloha
Price Range: $10—$135 (9 pack)
Alongside bedding and towels, Cariloha offer bamboo clothing including activewear, bamboo pajamas, women’s and men’s ethical underwear, and more. They have plenty of different styles of sustainable socks for men and women including ankle socks, sustainable athletic socks, crew socks, knee-high socks, and no-show socks. You can also choose from a huge range of designs, whether you want boring ol’ black or something fun like the neon Tropical Foliage.
For their ethical socks, the bamboo viscose is blended with several other fabrics including organic cotton and a small amount of nylon and spandex. Though some do contain polyester linings, so we’d recommend checking the material makeup before you buy.
All products are tested for harmful substances in accordance with OEKO-TEX® STANDARD 100. Cariloha has its own sustainably-run bamboo farm where they use zero pesticides before the bamboo fabric is safely made using GOTS-approved solvents in a closed-loop process.
Cariloha’s bamboo farm is in China’s Sichuan province and the bamboo is turned into bamboo fiber in China’s Hebei province. From there, the bamboo fiber travels to various manufacturing partners in China, India, Mexico, Turkey, and the US where it is woven and spun into yarn to make their sustainable bamboo socks. Some factories are Fair Trade certified.
The Certified B Corp’s box suppliers use materials that meet Sustainable Forestry Initiative Fiber Sourcing Standards and the paper packaging is FSC-certified. Cariloha supports several organizations through financial and product donations.
Why Choose to Support Ethical Sock Brands
It’s easy to overlook socks, but conventional pairs come with a surprising footprint. Most are made entirely with synthetics like virgin polyester, nylon, and other petroleum-based fibers that shed microplastics into waterways every time they’re washed. Their production relies on energy-intensive processes, toxic dyes, and chemical finishes, many of which end up polluting rivers and soil near manufacturing hubs.
Behind the seams, cheap, fast-fashion supply chains often mean low wages, unsafe working conditions, and little transparency about where or how socks are made. Add to that excessive packaging, short product lifespans, and landfill-bound waste, and you’ve got a deceptively big environmental problem in a small garment.
How We Found the Best Eco-Friendly Socks
You know when you can’t find a sock? You dig through the laundry, peek under the bed, and somehow still end up with one lonely pair.
Finding the most ethical sock brands was a bit like that, except instead of rummaging through mismatched pairs, we sorted through countless sustainability claims to find the ones that hold up.
We used our Sustainable & Ethical Fashion Guide as a framework, focusing on materials, supply chains, certifications, and overall business practices. And because we believe in walking the talk, we also personally tested several of these socks and in some cases, they’ve been rated against our own Sustainable Jungle Brand Rating System, which scores companies across four pillars: Nature & Animals, Communities & Wellbeing, Business Values & Governance, and Product Performance.
Materials
We looked for brands that use predominantly planet-friendly fabrics like GOTS-certified organic cotton, recycled cotton, bamboo, TENCEL™ lyocell, recycled wool, and ethically sourced wool.
Most socks aren’t compostable because even sustainable styles contain a small percentage of synthetic fibers (like elastane or nylon) for stretch and durability. That said, we favored brands using recycled synthetics or innovative lower-impact alternatives, and those working to minimize virgin polyester.
Relevant 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 prioritized brands that uphold fair labor, safe working conditions, and living wages, ideally backed by Fair Trade, WFTO, Fairtrade International, SMETA, BSCI, or WRAP certifications and audits. These steps help protect garment workers from exploitation and promote transparency across the production line.
Climate Action & Green Business Practices
We looked for brands going beyond the basics: carbon certifications, offsetting, plastic-free packaging, localized supply chains, recycling and take-back programs, and zero-waste manufacturing. These practices ensure sustainability extends well beyond the socks themselves.
Community & Giving Back
Finally, we favored brands that use their profits for good, whether that’s through charity partnerships, environmental activism, or circularity initiatives that keep textiles out of landfills.
FAQ: Sustainable & Ethical Socks
Are bamboo socks better than cotton?
It depends on how the fibers are produced. Bamboo socks can be more breathable, moisture-wicking, and antibacterial than conventional cotton socks, making them a great option for activewear or sustainable running socks. However, most bamboo fabric is made using a chemical-intensive viscose process, which isn’t always eco-friendly. Look for bamboo socks made in a closed-loop lyocell process or certified by OEKO-TEX® or FSC®, which ensures safer production. That said, organic cotton socks are often the better ethical choice when they’re GOTS-certified and free from pesticides and harmful dyes. Both bamboo and cotton can be sustainable. What matters most is how they’re grown, processed, and who’s making them.
Are wool socks compostable?
In theory, yes, but not always in practice. Wool socks made from 100% natural, untreated wool are compostable and will biodegrade over time. However, most sustainable wool socks (including those from leading eco-friendly sock brands) include a small percentage of synthetic fibers like nylon or elastane for stretch and durability. If you’re looking for compostable socks, choose ones that are plastic-free or contain less than 10% synthetic fibers. Brands using RWS-certified wool or ZQ Merino wool are good places to start. Having said that, we haven’t been able to find any that really stack up on both performance, and sustainability.
Are sustainable socks really worth it?
Absolutely. Conventional socks are often made entirely from virgin polyester or nylon, both derived from fossil fuels, and dyed using toxic chemicals that harm waterways and factory workers. By choosing eco-friendly socks made from organic cotton, closed loop bamboo, TENCEL™ lyocell, or recycled fibers, you help reduce carbon emissions, water pollution, and microplastic waste, while supporting brands with fair labor practices. In short, ethical socks are kinder to both people and the planet.
What are the most sustainable materials for socks?
The most sustainable socks are made from organic and renewable fibers such as GOTS-certified organic cotton, TENCEL™ lyocell, bamboo lyocell, and responsibly sourced wool. Recycled materials, like recycled cotton, also help reduce waste. The best sustainable sock brands combine these materials with minimal synthetics (ideally recycled) to ensure comfort, longevity, and a smaller footprint. However, it’s worth noting that synthetics, whether recycled or not, have broader environmental implications. They can shed microplastics, contribute to landfill waste, and release pollutants during production. Whenever possible, choose socks with the lowest percentage of synthetic fibers, as natural materials not only feel better but also lessen your impact.
How do you wash eco-friendly socks?
Wash your sustainable socks on a cold, gentle cycle using a non-toxic detergent. Avoid fabric softeners, as they can coat natural fibers and reduce breathability. To prevent microplastic shedding (for pairs containing synthetics), consider using a microfiber solution for your washing machine. Air drying is best. It saves energy and keeps your eco-friendly socks looking newer for longer.
Final Thoughts on Eco-Friendly Sock Brands
Clean socks, cleaner planet—that’s the simple aim behind eco-friendly socks. They might not be the most glamorous fashion staple, but they’re an essential part of any sustainable wardrobe. Just remember: the most sustainable pair is the one you already own.
If you can, darn those holes and give your current pairs a little more life. But when replacements are truly needed, this list of ethical and sustainable sock brands is a good place to start. Add some affordable sustainable socks to your wish list (and maybe a pair of ethical slippers for good measure), then check out our guide on what to do with old socks to keep every pair out of landfill.
And if you know someone whose sock drawer could use a refresh, help them take a small but meaningful step toward sustainability, share this list and help them pull on their next cozy, planet-friendly pair.

Really wish any of these brands offered socks that are actually plastic free!
Super hard to find given the stretch component. We’ll keep looking!
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!
