Our heated socks all feature our patented Toe Cap® heating element. The heating wires in the socks are sewn into the toe box and heat around the toes from below and above, exactly where the heat is needed. Thanks to our Merino Softtec® material mix, the socks offer maximum comfort. The battery is fastened with snaps and stowed under the sock waistband, where it cannot slip and always sits above the shoe. The heat levels are set either directly on the battery by pressing a button or even more conveniently: with the free Lenz heat app, the batteries can be controlled directly via Bluetooth via smartphone.
Whether you're an avid skier, extreme mountaineer, hunter or outdoor photographer, our socks are guaranteed to keep your feet warm. The different models all have the same Toe Cap® heating element and the same heating output. They only differ in the material composition and the padding - tailored to the different areas of application. Cleaning is very easy because the socks can be machine washed at 30°.
With a pair of heated socks from Lenz, cold feet are a thing of the past. These heated socks are more than just simple items of clothing. They represent the successful combination of advanced technology and high comfort to guarantee your pleasure in all your adventures, regardless of the low temperatures.
Correct application is crucial. The socks should not be heated only when you start to freeze. It is important that you let the socks run at least on the lowest level right from the start. So the toes can never cool down. If it then gets extremely cold, they can be set to the medium or highest level.
Not only do our heated socks stand for comfort, they are also an essential tool for increasing performance and concentration. Thanks to the constant and individually adjustable heat supply, they allow you to fully concentrate on your activities without being distracted by the cold. This reduces the risk of injury.

Heated socks provide more comprehensive warmth than heated insoles. While insoles only warm the sole, our Heat Socks with Toe Cap® technology target the toes – the most cold-sensitive part of the foot – and distribute heat comfortably across the entire forefoot. Additionally, the socks are more versatile and fit various types of shoes, from ski boots to hiking boots.
Depending on the chosen battery and heat setting, our heated socks keep your feet warm for 3 to 23 hours. On the lowest setting, the Lithium-Ion 2000 rcB battery lasts up to 23 hours, on medium heat about 10.5–12.5 hours, and on maximum heat around 7.5 hours. The rechargeable batteries can be fully charged overnight.
Heated socks with integrated heating technology are our most effective solution against cold feet. Lenz Heat Socks combine scratch-free Merino wool with electrical heating elements at the toes. This active heat source outperforms traditional thermal socks, especially in extreme sub-zero temperatures. For milder days, we also offer a wide range of high-quality Merino socks.
Our heated socks are machine washable at 30 °C. Remove the batteries before washing. Use a mild detergent without fabric softener and let the socks air dry completely – do not put them in the dryer.
Heated socks use integrated heating wires powered by rechargeable lithium-ion batteries. The heating elements are located in the toe area to warm the cold-sensitive spots. You can adjust the three or nine heat levels individually via the battery button or the Heat App. The same technology is used across our full range of heated clothing, from vests to gloves.
High-quality heated socks like Lenz Heat Socks are safe. The integrated heating systems operate at low voltage and feature multiple safety mechanisms against overheating. The heating wires are flexible and robust, and the batteries comply with all standard safety regulations.
Heated socks are ideal for winter sports enthusiasts, outdoor adventurers, and people with cold feet. Skiers, mountaineers, and hunters appreciate the reliable warmth in extreme conditions. They also provide comfort for anyone working outdoors for long periods. When paired with our Merino performance wear, they create a perfect layering system for maximum warmth and comfort.
Lenz heated socks feature fixed Toe Cap® heating elements that warm the toes from top and bottom. Using the battery, which is attached via snap buttons, you can select three different heat levels. Once activated, the built-in heating elements efficiently warm your feet within minutes.
