  Ventilated shoe soleUSPTO Application #: 20070022628Title: Ventilated shoe sole Abstract: A ventilated shoe sole is disclosed. This unique shoe sole is constructed with an elastic mid sole containing multiple cylindrical air spaces and multiple air vents arranged in parallel lines pattern across the sole, where the air vents communicates with their respective cylindrical air spaces underneath to allow air circulation around the bottom of the shoes. Therefore, heat and unpleasant foot odors can be rapidly expelled to the outside. In addition, the elastic mid sole provides an extra cushioning for the body weight. This shoe sole aids the design of comfortable and healthful footwear suitable for long time wearing.

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a ventilated shoe sole, and in particular to a unique sole that can provide adequate ventilation as well as good cushioning at the same time. [0003] 2. The Prior Arts [0004] If someone continuously wears impermeable leather or rubber shoes for a certain period, the feet will start to perspire and heat will accumulate around the bottom of the shoes. These provide the conditions for the fungus to grow, which will penetrate the corneous layer of the feet to cause fungus infections, such as athlete's foot, itching or red spots around the infected areas. [0005] The most commonly used preventive treatment is to use disinfectant/deodorant to spray around the bottom of the shoes to inhibit the growth of fungus and dispel unpleasant foot odors. The spray solution contains chemical composition that will inhibit the growth of mildew and fungus. Foot powder can be used instead of the aerosol sprays. But the best control of all is to keep the bottom of the feet fresh and dry all the time by wearing a pair of shoes with adequate ventilation and socks with good sweat absorbing capability. [0006] Some manufacturers claim that their insoles and shoes can effectively control foot odor, while others claim to promote general fitness and improve air circulation, by which the risks for the fungus to grow are lowered. However, as a matter of fact, what they have claimed in their products is very difficult to be substantiated from actual data. [0007] Yet, research efforts to make more comfortable footwear and even those with orthopedic support for the foot have never ceased. In these aspects, the ventilated shoe sole according to the present invention substantially reduces or obviates the limitations and disadvantages of the prior art. SUMMARY OF THE INVENTION [0008] The primary objective of the present invention is to provide a ventilated shoe sole that employs multiple cylindrical air spaces in the middle of the shoe sole and multiple air vents communicating with their respective cylindrical air spaces underneath to allow air circulation around the feet. Therefore, heat and foot odors can be rapidly expelled to the outside through air circulation around the bottom of the shoes. [0009] The secondary objective of the present invention is to provide a mid sole that is constructed with an elastic structure including a heel portion to provide an extra cushioning for the body weight and improve the shock absorbing ability. [0010] The tertiary objective of the present invention is to provide a ventilated shoe sole that aids the design of comfortable and healthful footwear suitable for long time wearing. [0011] To attain the above-mentioned objectives, the shoe sole comprises an outer sole that is the bottom layer of the shoe sole; a mid sole that has multiple cylindrical air spaces in the elastic structure and multiple air vents atop, where the air vents communicates with their respective cylindrical air spaces underneath to allow air circulation around the feet; and an insole that is placed over the mid sole and the outer sole. [0012] In accordance with the present invention, the air vents disposed in parallel lines pattern are able to communicate with their respective cylindrical air spaces underneath, through which heat and foot odors can be released to the outside by constant air circulation around the bottom of the shoes. [0013] In accordance with the present invention, the elastic structure and the cylindrical air spaces of the mid sole together acts as an air pump. When a wearer steps on the ground with one foot, most of the body weight is transferred to the bottom of the foot. This downward pressure forces out the air originally contained in the cylindrical air spaces at the bottom of the shoes as the elastic sole is compressed. Afterwards, the elastic body bounces back to its normal form as soon as the wearer lifts the foot from the ground. Since this is a repetitive process of walking, the elastic sole allows adequate air circulation around the bottom of the shoes worn by the wearer for a certain period of time. [0014] In accordance with the present invention, the central part of the insole has an open area that allows the air vents underneath to be exposed, so that the flow of air can be produced through the air vents and the cylindrical air spaces. [0015] These along with other features of novelty, which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the present invention, the operating advantages and the specific objectives attained by its uses, references should be made to the accompanying drawings and descriptive matter illustrated in preferred embodiments of the present invention.
