Perfect for winter sports, hiking and everyday use, the Heated Insoles W-TEC Ondrejnik II will keep your feet warm even during the coldest days. There are carbon fibers which provide the heating (with even heat distribution). The 3 heating modes allow you to adjust to the current weather conditions. 

Each insole is powered by three AA batteries that can last up to 6 hours. When the battery is low, the heating becomes less powerful. The batteries are stored in an adaptor that goes in a pocket with hook and loop closure, which you wrap around your calf. Thanks to the microUSB connection of the adaptor, it is also possible to use your own power bank (sold separatelyor a similar device containing a battery and is powered by USB. We recommend you use a power bank, as it lasts several hours longer than other devices!

The hook and loop strap is length-adjustable. The Heated Insoles W-TEC Ondrejnik can be conveniently cut to size as needed. Since the cable that goes from the insole to the battery is 40 cm long, you can use the insoles even when you’re wearing high boots. These insoles are so easy to use that anyone can do it.
