bou_005 Material / Cotton Nylon Polyurethane Size / 23-25cm 25-27cm Color / Ecru・Gray Made in Japan This is a representative item of BOU that has been carefully selected for materials and comfort. The outer yarn is made of 100% organic cotton, which is softer than regular cotton. The collar part is knitted in a special way like gauze to eliminate tightness as much as possible. The sole part is also designed with a plating technique, which exposes the nylon of the reinforcing thread that originally comes inside, and the organic cotton that feels good to the touch comes to the back side that touches the skin. The nylon yarn used for reinforcement is less "shrinking" than the polyester yarn used in general socks, so it is less tight on the soles of the feet and has a structure that does not feel stress or load. In addition, the plantar pile and instep part are made of thin jersey knitting, which is calculated to provide cushioning but not stiffness even when wearing sneakers or leather shoes. The design is inspired by medical socks for diabetic patients in Europe and the United States, and is also recommended for those who are prone to swollen feet. At a factory in Nara Prefecture, Japan's largest sock production area, each pair is carefully knitted and can be worn throughout the year regardless of the occasion. There are 1P and 2P, so please be careful not to make a mistake.
