Ventilation sole

Abstract

Disclosed herein is a ventilation sole. The ventilation sole includes an outsole (100), a midsole (200), a pumping part (300), air inlet parts (400), an air flow passage (500), and an air outlet part (600). That is, the ventilation sole includes the outsole, the midsole coupled to the outsole, the pumping part, the air inlet parts, the air flow passage, and the air outlet part, which are defined by the outsole and the midsole. When air is fed into the air inlet parts by the pumping action of the pumping part, the air flows through the air flow passage by the pumping action, thus reaching the air outlet part. While the air is discharged to the interior or exterior of a shoe, fresh air is supplied to the interior of the shoe.

Description

technical field [0001] The present invention relates to a shoe sole, especially a structure that allows air to flow in and out and has a pumping function inside the shoe sole, and naturally realizes the pumping function between the air in the shoe and the outside of the shoe through walking. Ventilated sole. Background technique [0002] Ordinary shoes are usually made of materials such as poorly ventilated leather or synthetic resin. If you wear them for a long time, it is inevitable that the temperature inside the shoes will rise and sweat due to the inability to circulate air with the outside, resulting in a humid atmosphere. At the same time, mold and the like Multiplication can also cause unpleasant odors or cause foot conditions such as athlete's foot. [0003] In order to solve the above-mentioned problems, various shoes with a ventilation function have been developed at present. [0004] The typical representative examples of the above-mentioned various prior arts ...
