One of the proposed options - insoles with heating. Let's try to figure out what are good insoles for shoes with heating, and how to choose the most convenient modification of insoles.
Disposable insoles with heating
The principle of operation of single insoles with heating is that the temperature is maintained by oxidizing the chemicals that make up the material. It can be activated carbon, iron powder or other natural materials. The temperature in shoes is + 38 ... + 45 degrees. Disposable insoles are made from environmentally friendly and hypoallergenic materials. Inconvenient chemical insoles with heating in that with poor access to air, for example, when working in sealed shoes or in shoe covers, the products are practically not effective. An alternative are the insoles made by their nettle fibers. Vegetable fibers improve blood circulation, which best affects the condition of the feet.

Insoles with heating on batteries
Heating in such insoles is due to the built-in heating element. Products are charged from an ordinary outlet with a voltage of 220 volts, charging time about 3 hours. When fully charged, the operating time of electric insoles with heating is 6-12 hours, depending on the air temperature and the quality of the shoes. The outer part of the insoles is made of a material that keeps the heat warm, moisture-proof and rather plastic, so that the product bends with the foot. Inside the wireless insoles with heating there is a grid of lithium and a carbon layer that maintains a comfortable temperature. There are types of insoles that can be charged in the car with the help of an adapter.
Insoles with heating on batteries
Each pair of insoles is equipped with a control unit that is attached to the outside of the shoe or leg of the leg. Standard batteries are used for power supply, but sometimes both ways of recharge are provided: from the batteries and the battery. Most often the device is equipped with a special switch, which allows you to turn on / off the insoles. The operating time of insoles is from 3.5 to 5 hours.
