This is a finely knitted sock made of extra fine merino wool blend. Wool is a material with natural warming but also moisture-transporting characteristics. So this sock creates an optimal climate for the foot and thus minimizes the risk of shoe chafing. Rib knit shaft and elastic knitted details in the foot for a good fit. Wool Liner sock is optimal to have as a first layer on colder days. Then combine with, for example, our boot socks to keep your feet warm even if they get wet.
