These ribbed crew socks from ROTOTO feature a dual-layer construction where the inner lining is made from wool for warmth, while the cotton outer surface protects against abrasion and extends the sock's lifespan. The ribbed design provides a secure, comfortable fit through the ankle and calf. Made in Japan with a blend of cotton, wool, nylon, and a small amount of stretch fibers, they are suited for everyday cold-weather wear and work well as part of a winter layering system.
