Socks made of Japanese traditional paper washi fiber, which prevents stuffiness, with 91.4% of people feeling dry (* result of in-house monitoring test). Easy to dry and stay dry even when sweating. Not only is it less likely to cause discomfort when wet, but it is also durable, water-resistant, and resists sagging. In addition, the five-toed construction makes it easy to feel and move, even the movement of the toes.
