Rohner trekking socks made with virgin wool and SeaCell active, a material infused with algae extracts. Through skin contact, the fiber releases important active ingredients such as proteins, vitamins, and carbohydrates. The silver contained in the material balances the bacterial flora and has antistatic properties. The optimal fit is achieved through an anatomical right/left knitting technique. There are special cushioning zones in the foot and instep areas. These trekking socks are composed of 27% polyamide, 25% cotton, 20% polyacrylic, 16% virgin wool, 11% Smartcel Sensitive, and 1% Lycra .
