Copper Business knee-high socks
Only at Boltersocken. Our Copper Business Knee-High Sock is versatile. Whether in the office, as a work sock, medical sock, or in your free time, sweaty feet will soon be a thing of the past. Merino wool inhibits odor formation and the thin copper sole provides a comfortable, dry wearing climate. With the right blend of OEKO-TEX®-certified merino wool and 100% fine copper threads, your feet stay at a comfortable temperature at all times, making this the perfect companion for leisure and work.
Since copper is attributed with antibacterial, circulation-promoting, and antistatic properties, we came up with the idea of knitting it together with our OEKO-TEX®-certified merino wool. Our merino wool socks with copper threads are truly impressive. The copper content eliminates bacteria, while the lofty merino wool provides exceptionally pleasant climate regulation. At the same time, the breathable properties of the merino wool allow your feet to breathe freely. With our merino wool socks with copper threads, you are doing something good for your health and body.
Our customers’ well-being is important to us, which is why we inspect the workmanship of every seam to prevent uncomfortable pressure points.

This is the Bolter sock manufacturer
Handcrafted in Vorarlberg, Austria, by a family business
"We uphold values that feel good deep down. And you can feel that every time you pull on our socks." Alexander Bolter

Why our merino and copper socks are so good for your well-being
Our merino wool socks absorb up to 30% of their own weight in moisture and, thanks to their fine fibers, are much more comfortable to wear than sheep's wool socks.
Combined with the ventilation channels typical of knitted fabrics, reinforced toe and heel areas, and a fluffy merino pile sole, they regulate the climate, keeping your feet dry for longer and at a comfortable temperature.
For even more comfort, we also offer socks without elastic. Socks with copper threads improve circulation and are therefore very popular with athletes and people with cold feet or circulatory problems.
Bolter merino socks are suitable for both women and men. The only differences are the color, material, and size.
