The present invention relates to a device for fomenting the feet of a user, comprising: a feet rest (10) for supporting the soles a cover (20) connected to the upper side of the feet rest (10), for covering the feet heating means (30, 30) having a heating structure on both of the feet rest (10) and the cover (20), or on the feet rest (10) a control unit (50) provided to store and control heat energy according to conditions set for the heating structure of the heating means (30, 30). Accordingly, the present invention is configured to be a heat storage type in which electromagnetic waves do not effect, and in which strong heat and week heat, and tension and relaxation coexist. Thus, the present invention may continuously induce the circulation of energy in a human body, thereby promoting the reduction of fatigue and the prevention of serious diseases and changing an unhealthy body into a healthy body. Particularly, the present invention enables a user to greatly concentrate on work due to appropriate stimulation which does not cause interruption to work when the user foments the feet and does some work at the same time, and to be subject to a sharp increase in the circulation of energy, thereby maintaining a good biorhythm and a vigorous flow of energy in 12 meridians in the body.La présente invention concerne un dispositif de fomentation pour les pieds dun utilisateur, comprenant : un repose-pieds (10) pour supporter les semelles un couvercle (20) relié à la face supérieure du repose-pieds (10), pour recouvrir les pieds un moyen de chauffage (30, 30) ayant une structure de chauffage à la fois sur le repose-pieds (10) et le couvercle (20), ou sur le repose-pieds (10) une unité de commande (50) prévue pour stocker et contrôler lénergie thermique selon des conditions définies pour la structure de chauffage du moyen de chauffage (30, 30). En conséquence, la présente invention est configurée de manière à être un type de stockage de chaleur dans lequel des ondes électroma
