SAVIOR HEAT Heated Socks for Men & Women, Brown, Size Medium — Merino Wool, App-Controlled 7.4V Rechargeable, 3 Heat Levels

SAVIOR HEAT Heated Socks are rechargeable, app-controlled Merino wool socks that deliver adjustable, long-lasting warmth for cold-weather activities.

These heated socks combine natural Merino comfort with built-in heating elements and two 7.4V batteries to keep feet warm for up to 12 hours. They pair with a Bluetooth app for remote temperature control and include a safety feature that automatically steps heat down after 30 minutes to avoid hot spots. Designed to fit comfortably inside boots, they work for skiing, hunting, hiking, work, and everyday winter use.

How do these socks manage temperature and safety?

The socks offer three heat levels—Low, Medium, High—and a smart safety mode that reduces power after 30 minutes to prevent overheating. You can re-enable higher heat manually if you need a boost. The heating elements are distributed to give balanced warmth across toes and the top of the foot.

• Three temperatures: ~104°F, 122°F, 149°F (approx.) for adaptable warmth
• Automatic step-down to Medium every 30 minutes for consistent comfort
• Manual override via on-sock switch or Bluetooth app
• Short 10-second quick-heat response when powered on

What are the battery life and charging details?

Each pair includes two rechargeable 7.4V 2200mAh batteries that attach to the socks. On a single charge they can supply warmth for extended outings—up to about 12 hours under lower settings—so you won’t need to swap batteries frequently during day trips.

• Two 7.4V 2200mAh batteries included with each pair
• Up to 12 hours runtime on lower heat settings; shorter on High
• Battery-level readout and timer control available through the Bluetooth app
• Wires and battery pockets positioned to fit inside boots comfortably

Will these socks work well inside boots and stay comfortable all day?

Yes—the Merino wool blend is slightly thinner than some Savior Heat models, designed to fit under ski or work boots without bulk. The wool wicks moisture, resists odors, and maintains softness after laundering, so you can wear them all day without sacrificing fit or breathability.

• Premium Merino wool for warmth, moisture wicking, and odor control
• Slim profile optimized for boots and layered footwear
• Machine-washable when batteries are removed, preserving softness
• Available in unisex sizes S–XL (US shoe sizes 5–14) for proper fit

How does the Bluetooth app improve usability in the field?

The Bluetooth app puts heat control and a timer on your phone so you can adjust settings without removing gloves or boots. It also shows remaining battery life and lets you schedule automatic shutoff, which helps manage power on multi-hour trips.

• Change heat levels and set a 0–180 minute timer remotely
• Monitor battery status directly from your phone or device
• On-sock switch provides a physical backup when a phone isn’t available

Who this is for: These SAVIOR HEAT heated socks suit outdoor enthusiasts and workers who need dependable foot warmth in cold conditions—skiers, hunters, ice-fishers, delivery drivers, construction workers, and everyday commuters. They’re especially useful for anyone who wants the natural comfort of Merino wool plus the flexibility of app control and long battery life, in a slim design that fits into boots and heavy footwear.
