Embodiment Construction

[0030] The invention, then, consists in the combination of: [0031] a sole 1 equipped, in the upper front-middle portion, with a broad cavity 2 and with a thin duct 3 apt to bring in communication said broad cavity 2 with the outside of the sole 1, through a unidirectional intercepting valve 4; [0032] a stretching structure 5 with high change in volume, made of flexible material with high elasticity, shaped and sized in a suitable way to be housed in the relaxed state at least partially in the broad shaped cavity 2 existing in the sole 1; [0033] an insole 6 made of waterproof material, such as leather, and fastened by gluing to the sole 1, on the front side equipped with flexible deformation 7, apt to cooperate with the broad cavity 2 shaped in the sole 1 to originate a pad-like projecting shaping, and with one or more holes 8 at said deformation 7, positioned so as to be clogged by the foot during walking, in the step wherein the foot compresses said pad in order to make it assume a...

Abstract

The combination of the sole (1)—equipped in the upper front-middle portion with the broad shaped cavity (2) and with the thin duct (3) therewith said broad shaped cavity (2) is brought in communication with the outside through the unidirectional valve (4)—of the stretching structure (5) with high change in volume implemented with flexible material with high elasticity, and of the insole (6) made of waterproof material equipped both with deformation (7) apt to cooperate with the broad shaped cavity (2) in the sole (1), to originate, under the action of the stretching structure (5), a pad-like projecting shaping, both with one or more holes (8), at said deformation (7) and in a position so as to be clogged by the foot during walking.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a sole and to means for airing the shoe thereto they belong, aimed at causing the air circulation therein during walking. [0003] 2. Description of the Related Art [0004] Shoes equipped with soles with cavities are known which, during walking, are alternatively compressed and then released, so as to act as pumps aimed at maintaining an air circulation inside each shoe in order to refresh the foot wearing it. [0005] The known air-circulating shoes in a case are implemented with flexible materials and have broad cavities on the heel (U.S. Pat. No. 5,138,775) which, due to the flexibility of the material therewith it is implemented, during walking they carry out a pump effect and force the air contained in such cavities to flow from the heel towards the front side of the shoe and then, through thin holes distributed in the insole, to flow towards the inside of the shoe in order to reach the foot...
