Shoe Sole With Ventilation, And Shoe Having Such A Sole

Abstract

The shoe sole ( 1 ) comprises a flexible chamber ( 6 ) arranged therein, with at least one inlet ( 5 ) and at least one outlet ( 9 ). The shoe sole (I) also comprises an inlet valve ( 15 ) assigned to the inlet ( 5 ), and an outlet valve ( 19 ) assigned to the outlet ( 9 ), wherein the flexible chamber ( 6 ) is arranged in the front region of the shoe sole ( 1 ), where an air inlet space ( 4 ) of the shoe sole ( 1 ) is also provided. The air inlet space ( 4 ) is connected by the inlet valve to the chamber ( 6 ) which is open to the environment via openings ( 2 ) in the insole ( 3 ). Moreover, the chamber ( 6 ) is corrected by the outlet valve to the outlet ( 9 ) on the outer face of the shoe sole ( 1 ) outside the insole ( 3 ). The chamber ( 6 ) is tilled almost completely with an elastically deformable material ( 16 ), which is such that, during its elastic expansion, it absorbs air and, during its compression, it releases air that has previously been absorbed. In this way, an air circulation that feels comfortable to the foot can be achieved in the shoe having this sole.

1 . A shoe sole ( 1 ) with a compressible chamber ( 6 ) containing an elastically deformable material with at least one inlet ( 5 ) and at least one outlet ( 8 ) and in each case an inlet valve ( 15 ) assigned to the inlet ( 5 ) and an outlet valve ( 19 ) assigned to the outlet ( 8 ), wherein the chamber is connected by the inlet valve and an air inlet space ( 4 ) to passages ( 2 ) opening on the upper face ( 13 ) of the shoe sole and wherein the chamber ( 6 ) is connected by the outlet valve to an outlet ( 9 ) on the outer face of the shoe sole ( 1 ) outside the upper face ( 13 ) thereof, characterized in that the chamber ( 6 ) is disposed in the front region of the shoe sole ( 1 ) and is filled almost completely with the elastically deformable material ( 16 ), which is such that, during its elastic expansion, it absorbs air and, during its compression, it releases air which has previously been absorbed.
