The "Marude Kotatsu" series uses patented technology to warm your body from the feet up. By using special materials to stimulate the "Sanyinjiao" pressure point on the ankle, your body will feel warm from the inside out. You will be enveloped in warmth just like in a kotatsu. [Just like kotatsu socks] The warm material wraps you from your calves to your toes, making them recommended for people who are sensitive to the cold. [Sleep Switch] Prevents chills while sleeping. It warms your feet by tightly covering the soles of your feet, where blood vessels are concentrated. The open-toe design keeps your feet comfortable and prevents them from getting sweaty while sleeping. When washing, please use a laundry net and wash with a mild detergent. Also, while the material used has excellent heat retention, it is prone to pilling due to friction during wear and washing. In that case, please use a lint remover.
