FREEHILL Merino Wool Heated Socks for Women Men-7.4V 16Hrs Battery

Details

• 【INSTANT RAPID HEAT】Powered by a 7.4V high-efficiency power system, our socks reach comfortable warmth fast. Premium metal alloy heating wires deliver instant penetrating heat from toe to heel the moment you turn them on. From cold to cozy in seconds — just immediate, reliable warmth that responds the instant you need it. Whether stepping out into a freezing morning or returning from snow, warmth is ready before you are.
• 【16HRS BATTERY & 4 SMART LEVELS】Two 7.4V 3000mAh batteries deliver up to 16 hours on Low—enough for a full day outdoors. Choose from 4 precise levels: Preheat (65°C/red breathing), High (62°C/red), Medium (55°C/white), and Low (45°C/blue). Type-C fast charging. With two batteries, you'll never run out of warmth during skiing, hunting, or any outdoor adventure.
• 【MERINO WOOL & COOLMAX PREMIUM BLEND】Crafted with 50% Merino Wool and 10% CoolMax, plus Polyester and Spandex. CoolMax actively pulls moisture away from skin, while merino wool naturally wicks sweat, resists odors, and stays itch-free. The stretchy fit conforms to your foot shape, and reinforced elastic binding prevents slipping or bunching inside boots. Feet stay dry and cozy even after 12 hours of wear.
• 【ALL-ROUND HEATING & COMFORT】Engineered for all-day comfort, these heated socks deliver even warmth across your entire sole—from toe to heel, not just one spot. Ergonomic design hugs your foot and calf, keeping socks securely in place without slipping or bunching inside heavy boots. Targeted support for long walks, hikes, or hours of standing.
• 【SMART CONTROLS & BUILT TO LAST】Long-press 2s to power on. Preheat mode (red breathing light) activates by default, then auto-switches to Medium after 5 minutes. Tap to cycle: Medium → Low → High. 4 LED indicators show remaining battery. Smart protections guard against short circuits, open circuits, over-charge, and over-discharge for complete peace of mind. Tested to last: 50,000 key-press life and functions normally at -20°C extreme cold. Ready for hunting, skiing, or daily commutes.
