Powered by a high-capacity 7.4V 3000mAh battery and our proprietary heating module, they deliver reliable warmth for up to 16 hours. Enjoy all-day comfort without the anxiety of your battery dying mid-adventure.
• UNPARALLELED COMFORT – A significant improvement over the original wool-blend model, we’ve enhanced the fabric composition with over 50% premium wool and added Coolmax fibers. This intelligent blend delivers superior warmth while actively wicking moisture, keeping your feet dry and comfortable during intense activities.
• SAFE、INTELLIGENT、DURABLE: The upgraded pre-heat mode boosts temperature rapidly before auto-switching to Medium, preventing burns and conserving energy. With a 4-LED power display and a battery system that protects against electrical faults, you can use it with total confidence. Built to withstand the elements, the module operates perfectly even at -20°C, with buttons tested for 50,000 presses.
• INNOVATIVE HIDDEN HEATING – We’ve completely redesigned the wearing experience. The heating wires are now strategically routed around the ankle to eliminate pressure points and bulkiness. Most importantly, our pioneering mid-layer heating design embeds the heating element between fabric layers. You won’t feel the hardware under your foot—just gentle, consistent warmth that prevents hot spots and protects against burns.
