Sole for footwear

Abstract

The invention relates to an improved sole for footwear with a convex or rounded shape, provided with a stabilizer, with a damping system and with an internal system for the rotation of air, which modifies the phase of contact of the foot with the ground in a roller, such that it transforms the process of reception of the ground (with the heel of the foot) and forward translation of the propelling forces (by means of the area of the metatarsus and toes) in a roller effect, obtaining the damping/stability/impulse effects, and the actuation of the airing system by means of a pad/wedge, the outsole thus configured allowing a rotation on the ground such that the inertia of the body and the vertical forces applied from the heel of the foot are more easily converted into horizontal propelling forces.

1 . An improved sole for footwear, characterized in that it is provided with a stabilizer, with a damping system, with an internal system for the rotation of air, and in that it has a convex or rounded shape, being configured by the following elements:
 the stabilizer ( 2 ) for securing the shoe and fixing the foot has the curve of the last and consists of a rigid sheet of a thermoplastic material or the like which encompasses the entire sole of the foot, and has holes ( 17 ) allowing the passage of air towards the insole.   the actual sole ( 3 ) of PU, thermoplastic material or the like, to which the stabilizer ( 2 ) is adhered at its upper part and the outsole/runner ( 5 ) is adhered at its lower part, and which integrates the pad/wedge ( 4 ); the sole ( 3 ) is provided with a network of channels ( 6 ) for the circulation of air.   The pad/wedge ( 4 ) of PU or similar material, with a convex or rounded shape in its base and with a preferably ellipsoidal plan ( 8 ), located in the central area of the sole ( 2 ) in the part of the heel of the foot, with a dual function of damping and absorption and impulse of the air of the airing system, and consisting of:
 a convex cavity ( 9 ) in the form of a suction cup the elastic composition of which allows its compression or sinking ( 12 ) with the weight of the body and the expansion or recovery of its initial shape ( 13 ) and ( 14 ); 
 air inlet holes ( 11 ); 
 cylinder ( 10 ) for the rising of air; 
   The outsole/runner of TPU material or similar material, with a high strength, which provides greater grip and maximum durability to the sole.   
     
     
         2 . The improved sole for footwear according to  claim 1 , characterized in that the stabilizer ( 2 ) provides stability and rigidity to the footwear and at the same time distributes the pressures along the sole, favoring the walk with a rocking effect and the securing of the foot, so that it does not twist towards the sides, upon giving way due to the weight of the body, since the wedge ( 4 ) is soft. 
     
     
         3 . The improved sole for footwear according to  claim 1 , characterized in that the pad/wedge ( 4 ) with a convex or rounded shape causes the damping/stability/impulse effects by articulating a natural movement bending similar to the sensation of walking barefoot over sand and which provides the footwear with the damping effect facilitating the “rocking walk” and, in turn, the compression thereof due to the weight of the body impulses the air through a system of channels ( 6 ) located inside the sole, generating a rotation of air which rises to the sole of the foot through holes ( 17 ) made in the stabilizer ( 2 ).
