Shoe having a single-piece sole contruction and active air ventilation

Abstract

A shoe, and production methods for such a shoe, having a single-piece sole construction, in which efficient air circulation in the shoe and thereby directly on the foot of the user of the shoe is made possible with every step of the walking movement of the user.

1 . A method for producing a shoe, having the steps of:
 providing a mounted upper with a perforated insole having openings in a joint region and/or a ball region of the shoe;   providing a single-piece sole construction with a solid sole body with one or more recesses in the solid sole body on the side that faces the insole by injection-molding in a corresponding injection mold;   providing an air pump device in a heel region of the shoe in one recess of the one or more recesses in the solid sole body;   providing a first air channel, which extends at least partially within the upper and is configured for feeding air to the air pump device, and a first valve, which is associated with the first air channel and is configured for allowing air to pass through only in the direction from outside of the sole construction to the air pump device, and affixing the first air channel to the upper;   providing a second air channel, which is configured for conducting air away from the air pump device, and a second valve, which is associated with the second air channel and is configured for allowing air to pass through only in the direction away from the air pump device; and   connecting the single-piece sole construction with the mounted upper by directly gluing the single-piece sole construction to the underside of the upper with the perforated insole in such a manner that the air pump device, the second air channel, and the second valve are positioned between the insole and the single-piece sole construction, in the one or more recesses, the second air channel being positioned between the insole and the single-piece sole construction so that the air pump device is connected to the openings in the insole via the second valve.   
     
     
         2 .- 6 . (canceled) 
     
     
         7 . The method according to  claim 1 , in which the first air channel is connected with the air pump device by way of the first valve, by means of connecting the single-piece sole construction with the mounted shaft. 
     
     
         8 . The method according to  claim 1 , in which the second air channel comprises one or more conduits that are formed by means of one or more recesses in the sole construction, and/or plastic hoses having openings along the longitudinal axis of the same, and/or a woven mesh. 
     
     
         9 .- 15 . (canceled) 
     
     
         16 . The method according to  claim 1 , wherein the step of providing an air pump device in a heel region of the shoe in one recess of the one or more recesses in the solid sole body comprises setting a lung plastic device into the one recess in the solid sole body.
