Are you still looking for a low budget sustainable Christmas gift? Or would you like to surprise someone with a small present? Then a pair of cool, sustainable socks is thé ideal gift! Because let’s face it, we can all use an extra pair of socks, right? Are you looking for colourful, cheerful socks for your niece or a pair of warm, woollen socks for your grandpa? At COSH! we collected the best sustainable sock brands that keep both small and big feet nice and warm!

What exactly is a sustainable sock?

A sustainable sock is first and foremost a high-quality sock. Cheap fast fashion socks that are discoloured and out of shape after a few washes are anything but sustainable! Therefore, we recommend that you invest a little more in a a pair with good quality that you can enjoy for a longer time.

From a sustainability point of view, we at COSH! also prefer socks made from natural materials such as organic cotton. This cotton is grown without harmful pesticides, which is better for people and the environment. Do you want to read more about the advantages of organic cotton? Click here. Do you see the GOTS label? Then you know you're on the right track. This label guarantees organic cultivation and good working conditions for cotton farmers.

Are socks with polyester and polyamide sustainable?

Unfortunately, it is still difficult to make a sock from 100% natural materials that is comfortable to wear. Therefore most socks contain a proportion of polyamide or elastane, derived from crude oil. These materials are not natural and also not biodegradable, which makes it difficult to recycle socks. However, this percentage of synthetic material is necessary to ensure good elasticity and comfort of the sock. Also, elastane makes your socks last longer, which is more sustainable in the long run.


A synthetic material based on petroleum also means that microplastics are released during washing. Do you want to avoid this? Then we recommend using a GuppyFriend. This clever bag catches the small plastic particles and prevents them from ending up in our seas and oceans!
