The fabric used for the lining of Japanese split-toe socks. This is a cloth woven with cotton yarn with fluffy surfaces. Since the touch is soft and warm, it is often used inside everyday socks for winter, with the fluffy surface facing towards the sole. In Noh, performers use white socks with flannel linings regardless of the season to highlight their beautiful and elegant feet. The lining of the yellow socks worn by kyōgen actors varies with the taste of the performer wearing them or the specifications of the manufacturers, but the fabric is often reversed so the fluffy surface does not face out.
