The excellent moisture absorption and desorption properties of silk keep the feet and the area between the toes dry. To add anti-odor and anti-bacterial effect, Anti-Odor Green Tea "ITO EN" Silk Toe Cover is made with catechin-containing fibers achieved by a collaboration with ITO EN, the world’s leading green tea beverage company. Catechin is a key component of green tea and is incorporated into the Tabio sock fibers made possible through unique technology exclusive to ITO EN.We recommend you wash the socks in a washing bag so that they wouldn't be lost.Why Five-Toe socks?Caring for Five-Toe & Two-Toe SocksThrough Tabio's production process, Five-Toe and Two-Toe socks may have threads that stick out between the toes. However, these threads are not defective; they strengthen the structure of the toe socks and help to keep the socks durable. We advise leaving them as they are since cutting these threads may cause holes and weaken the integrity of the sock.
