11 Best Organic Cotton And Bamboo Socks (2025)
The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.
We’ve researched and tested dozens of organic socks — these are our favorite options made of cotton or bamboo that are comfortable and sustainable across a range of price points.
When it comes to daily wardrobe choices, socks are typically left out of the equation. When in fact having comfy and cozy socks can elevate our mood, especially for those of us with chronically cold feet (no pun intended!). With regular socks, we find that they have holes after just a few wears or can be a bit scratchy, especially if they were made with artificial fabrics. Instead, we deserve comfy and conscious natural socks to keep our toes happy and our skin soothed.
Why consider organic cotton or bamboo socks?
We recommend organic socks because of their sustainability, environmental, and ethical features (as well as the health benefits). Organic materials such as organic cotton support sustainable agriculture as they are farmed using methods that have minimal impact on our ecosystems, compared to conventional fabrics. This includes crop rotation practices which help improve soil health and water conservation practices, to help prevent water waste. Organic cotton is also biodegradable, which helps fight pollution! Organic cotton producers also support socially responsible labor practices, meaning each purchase supports the ethical and fair treatment of garment workers.
It’s also important to note that because socks are in close contact with our skin, going for an organic fabric with fewer chemicals can prevent irritation — and also keep our feet dry/most comfortable, especially since bamboo is super breathable. Moreover, it’s soft and just feels great on our feet!
Our criteria:
We’ve researched, tested, and corresponded with many sock brands to choose our favorites compiled on this list. We’ve chosen the following brands based on fabric comfort, quality, texture, thickness, and fit — as well as sustainability and third-party certifications. We update this list regularly with our emerging favorites that meet the following criteria:

Customer Review | “These are great socks for spring, summer and fall temps. They are lightweight but warm enough for the cooler day. They don’t slide down in my walking shoes which is a huge plus!

Our Editor’s Review | “These socks are the true MVP of this review, and here’s why: I go through socks at a ridiculous rate. Even though I live in the desert, my feet are always cold. My floors are also hardwood. So, I’m constantly scooting around the house in socks or wearing them with my sandals to take the dog out. So many socks are too thin and wear out within weeks. These are not those socks; I’m convinced the wear-to-price ratio will make these more affordable long-term. Plus, the colors are gorgeous, and the cotton is so thick and cozy. Just trust me!” – Kayti Christian, Senior Content Strategist [Read the full review.]
