【Warm Wool Insoles】Recommended for cold feet in winter! The cold of winter often causes inconvenience, and the coldness of your feet can be felt most quickly, especially during daily work. HEHANDA's JW100 wool insoles combine natural wool and aluminum foil to generate heat and provide lasting warmth. They offer the warmth of winter, like being in front of a fireplace! 【Soft and Comfortable to Wear】The surface of the insoles uses natural wool (up to 1.2cm thick), providing instant warmth, and you can feel comfortable as your body warms up in about 2 minutes. The wool has been specially treated to remove odors, preventing foot odor and allowing you to use them with confidence in your daily life. (*A small amount of fluff may come loose, but this is normal and can be easily removed!) 【24-Hour Warmth】Aluminum foil is used on the bottom of the insoles, not only blocking cold from the ground but also helping to retain the temperature of the upper part. This keeps your feet warm and comfortable all day long, without feeling cold. The double-layer insulation effect of natural wool and aluminum foil allows you to feel warmth and softness from your feet to your whole body. 59-22
