Socks are an incredible way to bring an element of fun into your wardrobe. Fortunately, there are plenty of eco-friendly socks brands that keep your ecological footprint low and feet on a happy high. Whether ankle or crew, wool or cotton, hiking or dress socks, there’s a wide variety of quirkily designed, cleverly blended, and ethically created socks made from environmentally friendly materials.

However, socks present a unique challenge if you’re seeking completely natural bootees. Socks need to be stretchy, durable and supportive, and thus organic fibers are blended with a certain percentage of synthetic material such as nylon, elastane, polyamide and spandex. We’ve pointed that out in each pair we have selected. So, if you’re looking for socks with a conscience that defy early sagging and avoid the pesky toe-hole, look no further.

Ahead, our picks of the best organic socks that will keep your feet warm and your wardrobe sharp.

Pact Organic Socks

3 pairs of organic socks in pastel colors


Pact's socks are Treehugger's top pick for a combination of sustainable fabrics, ethical production, and affordable price point. These socks are Fairtrade certified, made from Global Organic Textile Standard (GOTS) certified cotton, along with nylon and elastane. Sold in packs, they are great value for money. The company has styles designed for women, men, and kids, in both basic solids and fun prints.

After years of use, we've found these socks don't pill or stretch out.

"We've been wearing Pact socks in my family for years, and many washes and walks later, they're still in great shape. They're often the first ones we grab from the drawer after laundry day." ~ Margaret Badore, Treehugger Associate Editorial Director

Harvest & Mill

From farm to mill, these socks are made entirely in the United States. Harvest & Mill told Treehugger that the cotton comes from farms that are both GOTS and USDA certified organic. Harvest & Mill uses no dye to color the socks, the three different light shades all come from the natural shades of the cotton plant. The socks are available in three women's sizes and three men's sizes.

The company is also carbon neutral, which means Harvest & Mill offsets all of its operations, including manufacturing and shipping. The company is also a member of Fibershed, a non-profit organization dedicating to developing sustainable natural fiber production.

Best Cotton

Kind Socks Watermelon Socks

Kind Socks Watermelon Socks

Kind Socks

The cute watermelon socks from Kind Socks, which is reimagining wardrobe essentials with cotton and kindness, are our favorite cotton feet warmers. The socks are made in India from 98 percent GOTS-certified organic cotton blended with two percent elastane.

To wash these breathable cotton socks, they recommend you turn them inside out and pop them in the washing machine at 104 degrees. You can expect a tiny bit of shrinkage the first time. A comfortable crew length, they come in two sizes. What’s more, they’re available in many delightful patterns—bumble bees, stripes, monstera leaves and even leopard and tiger prints. We think they'll put you in a good mood each time you put them on.

A champion for workers and farmers’ rights, business transparency and organic principles, Maggie’s Organics’ socks embody all these values. Soft, insulating and moisture-wicking, the Organic Wool Crew Socks are a good choice on cold days.

They’re a blend of GOTS-certified organic Merino wool, GOTS-certified organic cotton, along with nylon and spandex. This clever mix results in none of the itchiness of woolen socks. Instead, you  feel like your feet are wrapped up cozily in a cushy cardigan.

If you’re the kind of person who doesn’t want their socks to sneak up on to your calves, look no further than Conscious Step’s ankle socks. Available in two sizes, the socks are vegan, Fairtrade certified and made of GOTS-certified cotton, mixed with polyamide and spandex. Perching right on your ankles, the seamless toed socks are great for warm weather and come with a padded sole.

Taking it a step further, for every purchase of their socks, Conscious Step donates towards different humanitarian and environmental causes and name their socks thus. For every set of Socks That Build Homes sold, the company donate $1 to non-profit Habitat for Humanity for building safe housing for families in need. As a reminder, each sock is embroidered with a wee home. If you’re still not convinced, Conscious Step also contributes to the environment through 1% for the Planet.

A subtle rib adds just the right amount of dressy to make these socks from Organic Basics perfect for the office or pairing with a dress pant. They're available in five colors: black, navy, dusty rose, ocher, and cloudy blue. We also like that these socks have two size options, and can also be purchased as a multi-pack for a lower per-pair cost.

The socks are knit in Portugal from a blend of recycled polyamide, elastane, and cotton, which is certified organic and grown in Europe.

Girlfriend Collective Please Recycle Crew Sock

Girlfriend Collective Please Recycle Sock

Girlfriend Collective

Although these socks aren't organic, there are many things we like about them. Popular activewear brand Girlfriend Collective’s crew socks are envy inducing, whether at full length or scrunched down to a quarter crew. They are cozy, well-cushioned, and comfy. Available in funky neon (our personal pick!), seedling green, limestone and white colors, their compressive stitch is said to boost your blood circulation. Our testers found the fit to be quite snug, similar to a compression sock.

The socks are made from OEKO-TEX certified fabric created from 93% recycled water bottles, (which are BPA free) and spandex at a SA8000 certified factory, which ensures fair wages and safe conditions for workers. What’s more, once you’ve stretched them out of shape, you can even recycle the pair with their ReGirlfriend program.
