FIELD: items of personal and household use. ^ SUBSTANCE: between a sole and an insole of footwear in their calcaneal part, an air pump is arranged made in the form of a chamber which walls are made of pliable material. The other internal part of sole, excluding its calcaneal part, is made hollow, opened from its top face end and has vertical cross-section partitions furnished with apertures. The chamber communicates, through an inlet channel equipped with a return valve, with outside environment, and, through an outlet channel, which is also equipped with a return valve, made in the calcaneal part of sole, with a cavity of the other part of sole. The hollow part of sole features a compartment accommodating a heat-absorbing means providing for cooling of outside air supplied to user's foot. When heel lifts, underpressure is created in the air pump chamber. As a result, fresh air is inlet from the outside into the chamber cavity through the inlet channel. When heel presses on the back part of the insole, overpressure is created in the air pump chamber. The air is discharged from the chamber into the hollow part of sole and supplied, through apertures made in the insole, to user's foot. The air passes through the compartment containing the heat-absorbing means and is supplied cooled to user's foot. ^ EFFECT: increased usability of ventilated footwear at any temperatures due to the fact that the outside air is supplied cooled to user's foot; increased efficiency of ventilation. ^ 7 cl, 2 dwg |
