Experience exceptional warmth inspired by the comfort of a traditional Japanese kotatsu. These “Marude Kotatsu” (Like a Kotatsu) socks are designed to keep your feet and ankles deeply warm, even in cold indoor environments.
Using Okamoto’s proprietary warming technology, heat is retained around the ankle area—where cold is most easily felt—helping maintain overall foot warmth without bulk. The socks are soft, breathable, and comfortable for extended wear at home.
Perfect for winter lounging, working indoors, or relaxing evenings when you want cozy warmth without turning up the heater.
