WKS is a short and thin trekking sock containing merino wool, which is a unique natural material. A mesh zone is fitted across the entire instep area, which provides air circulation and moisture transport. The toe and heel sections are made of a two-layer smooth knit, which provides high mechanical resistance. Wool has excellent antibacterial properties and reduces unpleasant odours.  Material: 70% MERINO, 15% SILTEX, 10% POLYAMID, 5% LYCRA
