The Most Comfy & Versatile Sustainable Eco Friendly Socks

Whether you are a lover of socks or are simply looking to replace your old socks with some sustainable ones, you can use this list to help you choose from some of the best sustainable eco friendly socks on the market right now.

Before we get into it though, have you ever wondered where socks came from? Well, it turns out they date all the way to the Romans, who opted to wear them with sandals to keep their feet warm and dry.

The oldest pair of surviving socks were actually found in Egypt. They're a bright-colored, red-orange pair made of woven wool yarn, and dyed using plants (Smithsonian Magazine, 2018). Surprisingly intact, this old pair of socks survived about 1,700 years in a landfill before they were retrieved in the early 1900s.

While the concept has existed for quite some time now, socks were largely reserved for the rich, even after the Industrial Revolution. It also turns out that (as you may have imagined) stockings are actually an evolution of the sock.

Thankfully that is no longer the case, and socks have become an accessible item for many. So then, what should we be looking out for when choosing the most sustainable socks possible?

Here at The Eco Hub, we are committed to finding the very best sustainable brands. We independently review everything we recommend. When you buy through our affiliate links, we may earn a small commission. Learn more here.

Why consider sustainable, eco friendly socks?

The environmental impact of the garment industry is considerable no matter the item. From our t-shirts and jeans to our undies and our socks, opting for the eco-friendly option makes a considerable difference for the planet, for the people who make our garments, and for our health as well.

What to look for when buying sustainable and eco friendly socks

When looking for sustainable eco friendly socks, we consider the same criteria as we would when choosing anything else, from sustainable sweaters and ethical winter coats to fair trade pajamas and eco-friendly robes:

  • Natural or organic fabrics & materials like ethical wool
  • Ethical sourcing
  • Corporate responsibility

1. Natural or organic fabrics & materials

Here we consider what the garment is made of and opt for the best natural/organic fabric options available. These types of fabrics are as gentle on our skin and on the planet as they are on those who work with them.

2. Ethical sourcing

Next, we consider where materials are sourced and the practices used across the supply chain to create the final garment. This is very important because it's where we learn about how materials are made and how the workers who make our garments are treated.

3. Corporate responsibility

Finally, we consider every brand based on its commitment to high standards of performance, social responsibility, and environmental accountability. From net-zero carbon commitments to plastic-free shipping to charitable donations, we look for brands that really reflect what we stand for, and that we can truly stand behind.

A final word on ethical socks

Our rule of thumb when looking for any sustainable and ethical fashion is to always consider buying secondhand. To help with that, check out our list of 37 Online Thrift Stores For Secondhand Clothing. Ultimately, buying secondhand is the most sustainable and ethical solution when it comes to clothing. But when that is not possible and you need to buy new things, remember to support slow fashion for a much kinder alternative on our planet and its people, and the same goes for your sustainable sneakers.
