I purchased these for winter sports, but I'm selling them because I won't be using them. The size is approximately 24-26.5 cm in Japanese size. *This is a US size, so please use it as a guide. These are unopened, but they have been stored at home, so I would appreciate it if you could understand. *** Wool blend blue and green striped socks, 100% made in the USA for durability. - Brand: FARM TO FEET - Model Name: KITE - Material: 77% Wool, 22% Nylon, 1% Polyurethane - Color: Blue and Green Stripe - Features: 100% Made in USA
