Abstract (en)
The present invention relates to a device that allows the internal ventilation of shoes of the type including a sole (3) with which an upper (4) is associated. The device (1) has an air bag (5) associated with the sole (3) at the front region. The air bag (5) is connected to the inside of the shoe by means of a first intake valve (10) and to the outside of the shoe by means of a second discharge valve (15). While walking it is therefore possible to aspirate air and expel the associated moisture that are present inside the shoe, allowing to maintain an optimum condition for the foot inside the shoe. <IMAGE>
