Heated socks at Ski-Shop Ramser

At Ski-Shop Ramser, we focus on absolute top quality when it comes to heated socks. We only offer you the best brands and models that have proven themselves in practice. With our experience since 1977 in winter sports, we know exactly what it takes to keep you warm and comfortable in cold temperatures. 

Our heated sock sets contain everything you need to feel completely safe. We stand behind every sock we sell and guarantee maximum functionality and durability. Trust our expertise and experience the difference that high-quality heated socks can make to your outdoor adventures.

Heated socks from the brands Therm-ic | Lenz | BOOTDOC | Alpenheat

To maintain core body temperature in cold weather and thus protect the organs, the body draws blood away from the head, arms, and legs. While we wear up to 5 layers of clothing on our bodies on cold days, our hands and feet are covered with a maximum of 2 layers. Heated socks can help counteract this imbalance.

Heated socks operate via a lithium-ion battery that attaches to the cuff of the sock. This makes Lenz Socken easy to wash and allows for flexible recharging of the battery. Depending on the heat setting selected, heated socks provide up to 20 hours of warmth. Consequently, heated socks are not only suitable for winter sports but also for everyday use, ensuring pleasantly warm feet all day long. To ensure the battery-powered heated socks are ready for use the next day, Lenz has developed heated socks that can be fully charged overnight. For particularly high demands, we also carry the practicalski boot heater. Use the ski boot heater to heat the interior of your ski boots.
