These are chunky ribbed socks knitted alternately with two types of sock yarn. The toes, heels, and openings are thick with a heavier yarn. They are not tight and fit comfortably. They are thick enough to wear with shoes (like sports socks). The yarn used is Opal, made in Germany. The wool is breathable and warm. As it is sock yarn, it can be washed in the washing machine and is easy to care for. Size: Approximately 26-27cm (foot size) Length from opening to heel: Approximately 22cm Colors: Blue, red, yellow, charcoal, etc. Materials: 75% Wool (Superwash) 25% Polyamide (Nylon) Machine washable. (Water temperature below 40 degrees Celsius, use a laundry net) Do not use a dryer or fabric softener. The pattern of the dyed yarn will differ between the left and right socks.
