We stand behind the quality of our products

The Therm-ic medium thick heated technical socks are designed for runners in very cold climates or for those who have problems with toe circulation. Thanks to Smart Elastic Technology® they keep feet warm. The thin (2mm) S.E.T® heating line is unobtrusively integrated into the sock to provide gentle warmth around the toes without affecting the sock's fit on the foot and in the shoe. Durable polyamide fibres combined with elastane provide tension around the foot, the sock fits well and supports the foot on rebound.

The Therm-ic heated socks are used by members of the Swedish national biathlon team and also by competitors of the elite Ramudden team, which tops the Ski Classics long-distance series.

The socks are sold without batteries. Find all compatible batteries by clicking here. Three heat levels are available, to adapt the heat to your needs.

The socks are made with a proportion of merino wool, thanks to which they have excellent insulating properties even during aerobic activities. Merino wool regulates temperature and humidity efficiently, is breathable and insulates even when wet. It is able to absorb up to 33% moisture relative to its own weight, helping to keep the skin warm and dry.

The height of the socks/socks is up to the knees, thus offering greater comfort and also a quality fitting of the battery so that it cannot slide down even during long races, workouts and trips.

Size selection - recommendation
If you're on the borderline of sizes, choose a smaller sock size.

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.
