Why heated outdoor socks make all the difference
When you're doing outdoor activities in cold weather — winter hiking, high-altitude trekking, walking in the snow, mountain trips or bivouacking — your feet are quickly exposed to the cold, damp, poor circulation, possible frostbite or numbness. Even good footwear or technical socks are not always enough to keep your feet warm for long. Therm-ic's heated outdoor socks provide active, constant and even warmth — transforming the experience: warm feet, good blood circulation and prolonged comfort, even after several hours outdoors.
What Therm-ic outdoor heated socks offer
-
Targeted, even warmth, even in extreme cold — Thanks to patented ‘Fusion’ technology, the heating elements envelop the toes, foot and arch, ensuring effective heat diffusion where it is most needed.
-
Comfort, support and protection for outdoor activities— The socks are made from merino wool + technical fibres, combining insulation, breathability and comfort. Targeted reinforcements at the heels and toes reduce friction and pressure points, even in boots or high shoes, which is crucial when hiking or in the mountains.
-
Suitable battery life for long outings— With compatible batteries (S-Pack type), it is possible to obtain several hours—up to 14–16 hours depending on the battery and settings—of continuous heating, which is more than enough for a whole day outdoors.
-
Breathability & moisture management— Even when heated, the socks retain their breathable properties and wick away moisture, preventing the heat from becoming uncomfortable or your feet from sweating and then cooling down.
Who are these heated socks for?
- Hikers, trekkers, mountaineers, mountain or nature lovers exposed to cold, damp and wind — where foot thermoregulation is critical.
- People who are sensitive to the cold or have circulation problems (cold toes, Raynaud's syndrome, etc.), for whom constant warmth provides real comfort and protects against discomfort or even frostbite.
- For those who go on long outings or full days — winter hiking, ski touring, snow outings, hunting, tracking, etc. — and don't want the cold or damp to ruin the experience.
- For demanding users who want to combine technical performance, comfort, durability and versatility: active warmth + insulation + support + comfort, all in a sock designed for the outdoors.
Expert advice & best practices
- Combine socks + good shoes/high shoes + insoles if necessary: to maximise insulation, comfort and support, especially in difficult terrain or cold conditions.
- Choose the right battery and manage battery life: depending on the duration and intensity of the activity, adjust the settings to balance warmth and battery life. Check the charge before setting off.
- Careful maintenance: remove the batteries before washing, wash at 30°C max, without fabric softener, dry flat — to preserve the insulation, merino fibre and heating elements.
- Check the fit in your shoe/boot: the sock should not create excessive bulk, creases or pressure points, which could interfere with insulation or blood circulation.
- Adjust the heat setting according to the activity: intense effort (walking, climbing) → moderate heat to avoid overheating and perspiration; periods of immobility or intense cold → higher heat.
