We stand behind the quality of our products

Heated socks Therm-ic Ultra Warm Comfort S.E.T are made for skiers who want warm feet even in extreme conditions. Thanks to the patented Smart Elastic Technology (S.E.T), the heating runs along one discreet seam that warms under and above the toes without restricting the elasticity of the sock. The socks therefore fit the foot and the ski boot well.

Key benefits of the Ultra Warm Comfort S.E.T socks

  • S.E.T technology – the whole heating system runs in one thin, elastic seam, so the warmth spreads smoothly around the toes.

  • Merino wool and a thermoregulating knit – the medium-weight knit provides optimal insulation and breathability.

  • Moisture-Vent technology – micro-channels move moisture away from the skin to keep your feet dry.

  • Ergonomic fit – the socks hug the foot, ankle and calf precisely.

  • Up to 9 hours of warmth – depending on the battery used and the selected heating level.

Batteries are sold separately

The socks are supplied without batteries. To use them you need an S-Pack battery set. For socks with S.E.T technology we recommend the higher-capacity batteries S-Pack 1200 or S-Pack 1400B. If you want everything at once, take a look at the complete sets of socks with batteries: SET with S-Pack 1200 batteries or SET with S-Pack 1400B batteries.

Who the socks are for

These unisex socks are ideal for skiing, but they also suit cross-country skiing, snowshoeing, hiking and hunting. They come in five sizes from 35 to 47. If you are between sizes, choose the smaller size. You will find the Therm-ic brand in our range in other versions as well.

Care instructions

  • Remove the batteries before washing.

  • Turn the socks inside out before washing.

  • Machine wash at a maximum of 30 °C with a low spin speed.

  • Do not use bleach or fabric softener.

  • 01Active heatingA battery-powered heating element keeps you warm even when you stop moving.
  • 02Merino woolIt warms even when damp, wicks sweat and stays odour-free for days of wear.

Choose the battery life that fits your needs

The product is powered by Therm-ic lithium batteries, sold separately, so you can adjust battery life to match your daily routine. Press the button on the battery itself to switch between three heat settings – Bluetooth models also let you control everything directly from the Therm-ic app on your phone.

Pick your battery in the purchase box above: smaller-capacity batteries are a light choice for everyday use, while higher-capacity models offer significantly longer battery life at a slightly higher weight. Bluetooth versions also let you control and monitor the battery status directly through the app.

Control the temperature with the Therm-ic Heat Control app

Pair your batteries via Bluetooth and set the temperature directly from your phone, check battery status, and save your own custom profiles. Free app for iOS and Android.

Smart Elastic Technology (S.E.T)

Smart Elastic Technology (S.E.T) is a patented Therm-ic technology that runs the whole heating system in a single thin, elastic seam. The fine heating line spreads warmth under and above the toes without restricting the elasticity of the sock, so the sock sits well on the foot and inside the shoe.

Moisture-Vent

Moisture-Vent is a Therm-ic technology that absorbs moisture from the skin around the foot and carries it outwards through micro-channels. It also supports the breathability of the knit, so your feet stay drier and more comfortable.

Thermoregulating knit

The Therm-ic thermoregulating knit combines merino wool with technical fibres. A thermally insulating structure with channels retains heat while supporting moisture transport and breathability, complementing the heating system of the socks and keeping your feet comfortable.

Ergonomic fit

The ergonomic cut of Therm-ic socks hugs the foot, ankle and calf precisely and ensures a comfortable fit in your footwear. The heating system stays discreet and the sock feels pleasant to wear all day.
