Women's and men's knee socks contain silproX® with silver ions, which have an antibacterial effect and reduce the growth of bacteria and fungi. Bacteria are naturally destroyed by silver, preventing the formation of odours. You will appreciate this especially during sports activities. The knee socks have a wide, non-constricting cuff and a flexible zone across the instep to prevent them from twisting in the shoe. Sports knee socks in temperature class B are suitable for temperatures ranging from -5°C to +20°C.
