[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.
