THICK is the thickest sock in OTOR. Gray is also undyed, and the color is given by combining white and brown hair to make a thread. < plump and thick> Plenty of wool is used to wrap your feet tightly and warmly. < special pile knitting> The inside is pile-knitted, and you can feel the softness and warmth immediately through your feet. It also has excellent water absorption and moisture release, which makes it difficult for bacteria and germs to grow and smell. < Designed to not interfere with blood circulation> Since the ankle part expands and contracts as a whole and wraps around the foot, it does not interfere with blood circulation and is especially recommended for those who are sensitive to cold. < Machine washable for easy handling> The hair is washed many times during the manufacturing process, and after completion, it is pressed with steam. You can put it in the net and wash it in the washing machine with other laundry. After washing, you can feel even softer.
