NOVELTY - The utility model relates to the field of warm shoes, especially relates to a heating and warm-keeping long boot. The utility model claims a heating warming long cylinder boot, comprising a boot cylinder, a boot bottom and a boot surface; the boot cylinder is composed of a leather outer layer and a leather inner layer; the boot bottom; ankle and knee of the boot cylinder are provided with a graphene heating film; the outer surface of the boot cylinder is provided with a battery; the battery is electrically connected with the graphene heating film; the graphene heating film outer layer at the knee is provided with a graphene solar plate; the graphene solar plate is electrically connected with the battery; the graphene solar plate outer layer is provided with a transparent material. The utility model claims a heating and warm-keeping long cylinder boot, using graphene heating film with high efficiency of electric heat energy conversion rate and superconducting property, which can ensure stable heating performance, radiating uniformly, so as to the knee; The ankle and sole maintain a relatively warm and comfortable temperature, resist cold, keep health, and can release infrared, has bacteriostatic effect and heat preservation effect.
