## Abstract

The present invention relates to shoe construction to alleviate perspiration of user's feet and to get a more confortable walking:inner ventilation air is obtained mainly both by using a suitable special shaped inner foamed oversole, with interconnected open chambers, porous cushioned, memory retentent, with one or more hollows, under the footsole, in combination with a rear heel inner protrusion as a pump in addition to air ventilation got by the hollows. The air is drawn into and expelled from some intakes and outlets fitted in the rear heel portion, that can be partially or totally clogged by straps with buttons. To increase ventilation and to get it more homogeneous, in combination with pumping effect of the oversole with hollows, the higher upper portions are provided with some protrusions that surmount lower upper portions, where some holes for air passage are fitted.
