ABSTRACT:
A shoe includes a shoe sole having an accommodating portion and several ventilation holes formed through the side wall of the accommodating portion. A pressure-operated electric generator is provided in the accommodating portion and produces a voltage signal when pressure is repeatedly applied on the shoe sole during use. A cooling apparatus is provided inside the accommodating portion and produces cold air when the electric generator supplies the voltage signal to the cooling apparatus so as to cool the foot of a user. An air permeable and waterproof cloth covers the top surface of the shoe sole and surrounds the electric generator and the cooling apparatus except for the top surfaces of the same. A middle sole covers the upper portion of the assembly of the shoe sole and the cloth and has an accommodating hole formed therethrough so as to allow the top surface of the cooling apparatus to extend through the accommodating hole. A shoe pad is disposed on the top surface of the middle sole. Each of the middle sole and the shoe pad has several holes formed therethrough and communicated with the ventilation holes of the shoe sole in order to facilitate circulation of air in the shoe.
