Problems solved by technology

It is known that shoes for protecting walker's feet are manufactured by using leather or synthetic materials that makes ventilation not so perfect.
The shoes thus tend to accumulate moisture therein and this in turn can cause smell and even disease (e.g., athlete's foot or eczema) due to propagation of bacteria.
However, the conventional breathing shoe has the following drawbacks: Its air pumping operation is not active and functional.
Further, the effect of airbag pumping is poor.
It is often that a wearer in walking may easily feel tired due to the airbag inconsistent in hardness and no support for body weight lifting.

Embodiment Construction

[0016]Referring to FIGS. 1 to 7, a breathing shoe in accordance with the invention is shown. The shoe is shown as a sneaker but the character of the shoe could be superior to applied other kinds of shoes including dress shoes, casual shoes, golf shoes, sandals, slippers, etc. The shoe assembly comprises an upper 4 and a socklining 1, an insole 5, and an outsole 6. The socklining 1 is the subject of the invention as described in detail below.

[0017]An air chamber 3 is provided in a heel region. An airbag 2 is provided in the air chamber 3. Two outlets 21 are provided on a straight front end of the airbag 2 and a check valve 20 is provided on a curved rear edge thereof. The check valve 20 may communicate with air inside of the shoe. That is, the air only can be drawn into the airbag 2 but not exited therefrom.

[0018]An inlet 10 is formed integrally with an opening of the check valve 20 and communicates therewith. Two channels 11 are provided each having one end communicating with the ou...

Abstract

A sole assembly of a shoe includes an outsole (6); and a socklining (1) on top of the outsole (6) and comprising an air chamber (3) in a heel region; a airbag (2) in the air chamber (3), the airbag (2) including a plurality of front outlets (21) for expelling air from the airbag (2) forwardly, and a rear check valve (20) for permitting air to enter the airbag (2) but not to exit the airbag (2); and a resilient support (22) in the airbag (2).

Description

BACKGROUND OF THE INVENTION [0001]1. Field of the Invention[0002]The invention relates to footwear and more particularly to a shoe (e.g., sneaker) having an improved airbag and ventilation arrangement.[0003]2. Description of Related Art[0004]It is known that shoes for protecting walker's feet are manufactured by using leather or synthetic materials that makes ventilation not so perfect. The shoes thus tend to accumulate moisture therein and this in turn can cause smell and even disease (e.g., athlete's foot or eczema) due to propagation of bacteria.[0005]Recently, shoes having a ventilation arrangement have been commercially available. This shoe has been granted U.S. Pat. No. 6,434,858 B2. Typically, such shoes are so called breathing shoes and the shoe comprises a pump installed under an outsole only for expelling air, a one-way valve for allowing the introduction of air into the pump, and an air discharge tube connecting with the valve for purging air out of the shoe.[0006]However...
