Description

Thermal shoes and their thermal insoles

technical field

The utility model relates to the technology in the field of shoe materials, in particular to a warm shoe and its insole.

Background technique

In the cold winter, people tend to feel cold feet. People feel that their feet are still cold even though they are wearing shoes. For this reason, people often add one deck shoe-pad at the bottom of shoes, utilize shoe-pad to be foot insulation. But traditional shoe-pad, it only has simple insulation effect. When in use, it is still necessary to rely on the body temperature of the human body for heating. Therefore, in the cold winter, traditional insoles cannot provide better warmth and cold protection for the feet. For this reason, people have invented heating shoe-pad. As the name suggests, the heated insole is to heat the insole through some heating devices, so that the insole itself generates a certain temperature, thereby providing a better effect of keeping the feet warm and cold. Existing heating insole, it is mainly by placing lithium battery and heating device in shoe pad, provides electric energy for heating device by lithium battery, utilizes the heat that heating device produces to realize warming for people's feet. But the existing heating insole can only provide electric energy for the heating device through the lithium battery.
