Sustainable materials

We aim to produce our socks out of the most sustainable materials.

At Star Sock we like to work with sustainable materials as much as we can. We even strive to produce 80% of our socks exclusively out of sustainable materials by 2020. 


We use ECONYL®, a high-quality Polyamide yarn made from nylon waste, in the manufacturing of our socks. ECONYL® is developed through an innovative industrial regeneration process; turning nylon waste, such as recovered fishing nets and plastics, into new yarn. In 2013, together with Aquafil and the ECNC Group, we established the Healthy Seas Initiative in order to collect old fishing nets and turn them into new ECONYL® yarn. We love this product, as it not only decreases our impact on the earth’s limited resources, but also contributes to keeping our seas clean! 

Recycled Cotton 

In the garment production a lot of cutting waste can be found. This ‘waste’ is often good quality cotton that is thrown away. In our production process these flakes are used as the base material for regenerated cotton yarn. This is a perfect yarn for our sports and workwear socks. Over 40 percent of our total production volume in kilos is made out of recycled cotton yarn, displacing the need for virgin cotton and significantly reducing the environmental impact of production. 

Organic Cotton

Although cotton is a natural and very comfortable product, it is not necessarily an environmentally friendly fibre. It is a thirsty crop, requiring a lot of water and a lot of pesticides. We are therefore gradually increasing our use of certified organic cotton. To achieve this we work with organisations like Organic Content Standard (OCS) and the Global Organic Textile Standard (GOTS) They help us verify, among other things, if our socks actually contain the amount of organically grown material we believe they do. Why? Because we want to make sure our communications about these percentages our honest and correct. These organisations also see to it that our cotton is produced without using chemical fertilizers or pesticides. The result is a high quality cotton that is better for the farmer and the environment.
