Heated Insoles, Rtdep 7.4V Rechargeable Foot Warmers, Heated Shoe with 3000mAh Battery Winter Heated Insoles for Men and Women, Skiing, Hunting, Hiking, Camping Outdoor Sports

【Innovative 2-in-1 Design: Heated Insoles + Heated Knee Wrap】This foot warmer set stands out with a unique battery pocket on the heated insoles—acting as a shared power source, it fuels both the heated insoles and heated knee wrap at the same time. Better yet, the battery pocket can also work independently as a heated knee brace, letting you switch between warming feet and knees based on your needs.​【Advanced Heating System & Precision Control】Our heated insoles adopt carbon crystal nano heating material, covering the entire foot to keep your feet warmer evenly and quickly. The knee-wrap-style dual-heat control switch has anti-misoperation protection and 3 temperature levels, so you can adjust the heat of the heated insoles or knee wrap separately to match your comfort.​【Soft PU Base & Light Arch Support: Comfortable Foot Warmer】This rechargeable foot warmer is made of soft PU material, with an air shock-absorption design at the heel to reduce foot fatigue. The lightweight arch design fits your foot’s arch curve perfectly, distributes foot pressure, stabilizes your walking posture, and keeps your feet warmer even during long hours of use.​【Tailored for Cold-Weather Outdoor Activities】These heated insoles come with extended battery straps (built-in anti-slip silicone) and a 65cm power cord—they attach firmly to your calves or boot shafts, no slipping or shifting even when you’re moving. Perfect for skiing, hunting, hiking, camping, or any winter outdoor activity where you need to keep your feet warmer.​【 Longer-Lasting Feet Warmth:7.4V 23.1Wh Battery】Powered by a 7.4V battery, these heated insoles heat up faster than 5V models. No dedicated charger is needed—just use your phone charger for convenient recharging. The high-capacity battery ensures long-lasting power, keeping your feet warmer all day long in cold weather.
