Goldwin socks. Brand new, unopened. The following is quoted from the official website: These socks are made with paper yarn and feature a dry feel. They also excel in supporting the arch of the foot. The unique, rough texture of the paper yarn fiber is highly absorbent and releases moisture well, reducing unpleasant stickiness and stuffiness, and maintaining a dry feel. In a monitor survey of general users, 182 out of 187 people felt "dry," and 77 out of 80 people felt "dry" when worn in rainy weather (*). In addition, they have more than 5 times the strength (compared to our products) of regular sports socks and are resistant to holes. Furthermore, the arch support structure on the sole of the foot supports the lateral arch. By supporting the arch and preventing its collapse, it not only absorbs the impact on the legs during landing but also allows the arch of the foot to act as a spring, providing propulsion. The opening is switched to a gentle nylon yarn. They are finished with a short length that reveals the ankle. *Results of a monitor survey of the relevant product Fabric Nylon, Other fibers (paper), Others Country of Origin Japan Size L size (26-28cm) Color Off-white
