Shoe Having Active Air Ventilation

Abstract

The invention relates to a shoe, comprising a sole construction, which has an upper sole part and a lower outsole part and an air-pumping device having a pumping vol-ume, an air-supplying device, which is connected to the air-pumping device, an air-discharging device, which is connected to the air-pumping device, wherein the upper sole part, the lower outsole part, and the air-pumping device are de-signed in such a way that air in the amount of the pumping volume can be sucked into the air-pumping device through the air-supplying device from outside the shoe and above the upper sole part due to the unloading of the sole con-struction during the walking motion of a user, air in the amount of the pumping volume can be discharged into the interior of the shoe through the air-discharging device due to the loading of the sole construction during the walking motion of the user, and the pumping volume of the air-pumping device is at least 5 ml, in particular at least 10 ml.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a shoe with a sole construction which during every step of the walking motion of a user enables efficient air circulation in the shoe, and thereby directly at the foot of a user of the shoe.BACKGROUND OF THE INVENTION[0002]A shoe is composed of two main parts, namely the upper part called the upper, and the lower part called the base. The upper can comprise an inner upper (lining), intermediate upper (interlining) and outer upper (vamp). The base is composed of a sole and can comprise an inner sole (insole) and an outsole. One or more midsoles can be provided between the insole and the outsole.[0003]Nowadays, shoes are known that are equipped with devices in the sole which promote the circulation of air in the shoe, whereby the internal moisture in the shoe is to be reduced to improve foot comfort of the user of the shoe. This known type of shoe generally provides hollow connections which are accommodated interconnected in...

AI Technical Summary

Benefits of technology

[0046]Fresh air can thereby be sucked in by the air-pumping device over a relatively large area. In particular, water ingress into the shoe from the outside is prevented when

Problems solved by technology

However, it has been found that no efficient supply of fresh air is possible in this manner.

The drawback of this type of shoe is the lack of effectiveness of the air circulation in the shoe due to inefficient air intake by use of the air-pumping device.

However, it has shown that the pumping mechanism by merely havin
