The far-infrared effects of charcoal also improve blood circulation, gently warming your feet. Unlike traditional charcoal-treated fibers, the yarn itself is made of charcoal, so the charcoal effect lasts semi-permanently, even after repeated washing. As a result, the far-infrared and antibacterial effects will continue to keep your feet warm until the socks wear out. [For winter chills and sensitivity to cold] These socks are perfect for cold floors, especially when doing housework or laundry, where your feet are prone to getting cold. They gently warm your feet with far-infrared rays. These slightly thick pile socks are also great for outdoor activities, so they're perfect for those working outdoors. [Plenty of natural fibers] Although a small percentage of synthetic fibers are used for stretch, the majority of the fabric is natural. The cotton and charcoal-blended fibers are gentle on the skin and offer a comfortable, addictive feel. Recommended for those who don't like synthetic fibers. [Roomy opening] The opening is designed without ribbing, so you can wear it comfortably without feeling tight. It reduces the marks left by socks due to swelling in the evening, so it is recommended for those who have been concerned about this. [Recommended as a gift] This is also a great gift for family, friends, and loved ones who suffer from cold sensitivity or sensitivity to the cold. Perfect for Mother's Day, Father's Day, Respect for the Aged Day, birthdays, Christmas, Valentine's Day, White Day, and more.
