The Karrimor Trekking Sock achieves protection level 4 - the highest there is - making them excellent for winter treks and hikes. The combination of anatomical design, advanced padding and support provides excellent comfort and protection: stay-up pro-rib and Anti-Ruche construction means they won't slip down your shin, while the ankle support provides a high level of stability. Extra padding on the arch of the foot and a fully cushioned sole help to absorb the forces of each footstrike when you're walking. The fabric is 40% acrylic, 40% wool and 20% polyamide, and they are machine washable.
