Footwear sole

Abstract

Shoe insert ( 1 ) comprised of numerous elements that provide shock absorption, elements that are made up of numerous cavities ( 2 ), each corresponding with pivots or shock absorbing ( 3 ) elements, which extend out from the bottom part of the insert; shock absorption elements ( 2, 3 ) configured in such way that, when compressed by the user's weight, they compress and absorb the shock that is produced by the stepping action, thus achieving a sensation of well being and comfort.

1 . Foot insert ( 1 ) manufactured as one-piece from polymeric material with a low level of residual deformation, soft enough to provide shock absorption when compressed, but of sufficient quality for it to spring back and not permanently deform,
 comprising   a plurality shock absorbers consisting of multiple cavities ( 2 ), each corresponding with the pivots or shock absorbing ( 3 ) elements, which extend out from the bottom part of the insert,   and where the aforementioned shock absorbing elements ( 2 ,  3 ) are configured so that when compressed by the user's weight, they give in and absorb the shock produced by stepping.   and it is characterized in that in the mentioned cavities ( 2 ) which make up the inside of the shock absorbing elements ( 3 ), an inner base or pivot ( 4 ) has been inserted, which does not entirely fill de cavity area of the shock absorbing elements ( 3 ) because this way, the weight causes the outer ring ( 21 ) to give in until it is supported on the base or inside pivot ( 4 ), which in turn acts as a stronger, second shock absorber, which at the same time helps the shock absorbers to spring back to their initial position when the weight of the foot stops exerting pressure over them and do not lose efficacy with use or from walking.   
     
     
         2 . Insert in accordance with  claim 1  where the inner pivots ( 4 ) are configured to adapt to each of the points of the foot they come in contact with and depending on the weight they support at the time, they produce a type of controlled support at the bottom of the foot. 
     
     
         3 . Insert in accordance with  claim 1 , where the insert ( 1 ) also incorporates multiple channels ( 5 ) that connect the shock absorbing elements ( 2 , 3 , 4 ) which are configured to circulate air from the heel area to the sole. 
     
     
         4 . Shoe that is characterized in that it is comprised of an insert as the one described in  claim 1 .
