You can feel the warmth within seconds of turning on the switch, efficiently warming your often-cold feet and alleviating overall body chill. They can also promote blood circulation, helping to prevent cracked heels and pain that often occur in winter. The temperature can be adjusted steplessly from 35 to 70°C via a smartphone app, and it also supports timer settings and a rapid heating function. By connecting the battery via Bluetooth and making detailed adjustments within the app, you can use them comfortably in a wide range of environments, from indoors to winter sports. For safety, please disconnect the cable from the battery after use. The included batteries are two dedicated rechargeable 5000mAh batteries (totaling 10000mAh). They are lightweight and thin, with rounded corners, so they feel comfortable even when stored in the dedicated pockets, and are comfortable to use for long periods. They can be used continuously for up to approximately 8 hours and have a high level of safety, having obtained PSE certification. They are ideal for outdoor work in winter, fishing, skiing, touring, and other activities in cold environments. Please fully charge them with the included Type-C cable before use. The sock body uses a thick, soft material that feels good against the skin, allowing even those with sensitive skin to use them with confidence. They are not only excellent at heat retention but also have excellent absorbency, breathability, and elasticity, and are highly durable. You can wear them comfortably as regular socks by turning off the heating function. They are unisex due to their elasticity and fit feet from 23 to 27cm. The improved dedicated pockets prevent the battery from slipping, reducing anxiety while walking. They are useful for commuting, going to school, traveling, the office, home, as well as skiing, snowboarding, hiking, mountain climbing, motorcycling, and various other situations. They are especially recommended as a cold-weather item for those suffering from joint pain, chronic cold feet, and joint stiffness. The set includes one pair of heated socks, two 3.7V 5000mAh dedicated batteries, one charging cable, one laundry net, and one Japanese instruction manual.
