Frequently asked questions

What is your role in the Healthy Seas Project?

Together with our partners, Aquafil and ECNC, Star Sock has launched an initiative called ‘Healthy Seas, a journey from Waste to Wear’. The main objective of the Healthy Seas initiative is to remove waste, in particular fishing nets and other marine litter, from the seas. These nets will be upcycled into new ECONYL® yarn from which we can make new high-quality products. As a Healthy Seas ambassador we aim to help the project grow. As well as this we are proud to produce socks partly made from used fishing nets. All socks made with ECONYL are part of a movement towards healthier seas. Learn more.

Do you have a bio or eco collection?

When we began working on sustainability we decided to set ambitious targets for the amount of sustainable materials we use. We work towards improvements step by step with the aim of achieving our goals by 2020. We already offer various sustainable products, ranging from ECONYL® socks to regenerated and biological cotton. Please contact our sales team for more information ( or +31 (0)13 - 52 31 400).

Where do you produce your socks?

In 2013 we produced 55% of our socks in China, 35% in Portugal and 10% in Turkey. These percentages vary every year, as each country has its own specialisation. We focus on long-term supplier relations and cooperation based on mutual trust,and generally work with most of our suppliers for many years. We feel working in this way is the most profitable for our suppliers, our customers, and for ourselves in the long term. However as the world of textiles is constantly evolving, in our sourcing policy we keep the highest standards and only start to work with suppliers we believe are capable of joining us in our sustainability journey.  

How sustainable is the Star Sock head office?

The Star Sock head office is both innovative and sustainable, and was designed to reflect the ‘green lifestyle’ of Star Sock owners Eric and Angelie Roosen. The roof of the building is ‘alive’ and can best be described as a beech tree covered slope. The building supports an ingenious system obtaining heat from the ground and sun and re-using it within the building. The glass walls of the offices are built around an open inner courtyard, which brings the outside in and vice-versa. We have recently installed 8000 kWh of solar panels, We can now charge our Electric Tesla car with this energy. If you visit our office with your own electric car, we will share our energy with you!

Do you have information that your customers can use in their own CSR communications (e.g. customer statement, press release etc.)

Yes, we not only offer comfort for feet, but also for our customers themselves, by encouraging them to source more sustainably. We believe transparency in communication is part of being sustainable. We offer our customers information related to Star Sock and sustainability, which can be used in annual reports or other external communication. Please contact our office for more information: +31 (0)13 52 31 400 or

What is the definition of ‘positive impact’ for Star Sock?

By 2020 we aim to produce our socks in the most sustainable way possible, using sustainably sourced materials. As well as this we want to inform, inspire and encourage our stakeholders and invest in a better world, for example by participating in the Healthy Seas initiative. In social terms we see it as our responsibility to ensure that all people that are involved in the manufacturing of our socks work under fair conditions. From the cotton farmer to the factory worker, each choice we take and each step we make is aimed at making things better, for our clients but also for the people making our socks.  

I see you use a lot of recycled materials, does this affect the quality of your socks?

At Star Sock all our developments and designs are focussed on offering comfort for your feet. A sustainable design must never compromise this goal, and therefore we choose our products very carefully. Innovation and sustainability go hand in hand, and we rigorously test our products both internally and externally (SGS, Intertek). In this way we can ensure their quality lives up to our high standards. 

How many fishing nets has the Healthy Seas Initiative recovered up until now?

The Healthy Seas only started in 2013, but is rapidly expanding. More and more businesses and NGO’s want to help clear our seas. As a result, more and more abandoned fishing nets and other marine litter can be regenerated into new yarns. At Star Sock we are proud to make our socks out of this great material.
