Heated Insoles W-TEC Ondrejnik

Perfect for winter sports, hiking and everyday use, the Heated Insoles W-TEC Ondrejnik 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 7 hours. When the battery is low, the heating becomes less powerful. The batteries are stored in an adaptor that goes in the pocket on a Velcro strap, which you wrap around your calf. Thanks to the microUSB connection of the adapter, it is also possible to use your own powerbank (can be purchased) or similar device containing a battery. 
The Velcro 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 40cm 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.
