Frequently asked questions about recycled socks:
Our recycled socks are made from ECONYL yarn; a high-quality fabric made from old fishing nets (ghost nets) retrieved from the ocean. This is combined with organic cotton, giving you a super comfortable sock that is sturdy, soft and eco-friendly.
Old fishing nets are one of the most dangerous types of plastic waste in the sea. They float around for years and pose a threat to fish, dolphins, turtles and other marine life. By cleaning up those nets AND making something new out of them, you are directly helping to create a cleaner ocean; just by wearing socks.
Sure. They are breathable, form-fitting and remain soft even after frequent washing. The combination of recycled nylon and cotton ensures long-lasting comfort and strength. Perfect for everyday use: at home, at work or on the go.
Wash them at a low temperature, 30 to 40 degrees, with a mild detergent. Turn them inside out and air dry (do not tumble dry). This will keep them nice, soft and strong longer, and prevent unnecessary wear.
Each pair of recycled socks helps reduce the plastic soup. By reusing old fishing nets instead of producing new raw materials, you save energy, water and emissions. Plus, you support direct cleanup efforts in seas and along the coast. So you make an impact with every step.
More than that. They are super soft, breathable and feel sturdy. Thanks to the clever material, they stay put and don't shrink easily. You won't feel any difference, except that you know you're doing the right thing.
ECONYL is a circular material, made from waste that would otherwise remain in the sea or landfill. Think fishing nets, carpet scraps and industrial plastic. It is fully recyclable, strong and of high quality. Sustainable and practical.
Absolutely. Pair your socks with a reusable water bottle, lunchbox or eco bag and you have a sustainable daily set all together. Good for yourself and good for the world. So you make conscious choices every day, without compromising on convenience or style.
Yes, that's no problem at all. Sizing is leading: women's sizes run from 36 to 40 and men's sizes from 41 to 46. As a woman, do you have size 41 or 42? Then the men's socks will fit perfectly. Do you as a man have a smaller size (for example 39 or 40)? Then feel free to choose the women's socks, especially with the neutral designs such as the 'Classic Duo' or solid colors. The fit is universal and comfortable for any foot.
No, absolutely not. Although the base of the yarn is recycled nylon (ECONYL®) derived from fishing nets, it is combined with 100% organic cotton. The recycled nylon provides the strength and abrasion resistance of the sock, while the organic cotton provides the soft feel and breathability. This very combination ensures excellent moisture management and fresh feet throughout the day.
Ghost nets (ghost nets) are fishing nets that have been lost or deliberately left in the sea. Because they are made of strong plastic, they do not decay. They float around and unintentionally catch fish, turtles and marine mammals, and damage coral reefs. By buying Healthy Seas Socks, you are supporting the dive teams who remove these nets from the oceans, then process them into new raw materials for our socks.
Sure! In our assortment you will find specific 'Sport Duo' packages. These socks have the same sustainable properties, but are optimized in design and fit for an active lifestyle. Thanks to the mix of materials, they stay well in place while running, working out or hiking and wick away moisture effectively. The classic models are also great for lighter activities such as hiking or golf due to their sturdy quality.
The socks are produced pre-washed and shrink-free, provided you follow the washing instructions. We recommend washing the socks at up to 30 or 40 degrees. Because the material is partly synthetic (recycled nylon), the socks dry very quickly on the clothesline. Please prefer not to put them in the dryer; this is not only better for the preservation of the socks and the elastic, but also much more sustainable for the environment.
