An insole for shoes comprising, associated one another, a resting layer for a sole of a user's foot, made of soft and breathable material, a padding layer, made of soft and breathable material that can adapt to the shape of the sole of the user's foot, a layer for absorbing impacts and vibrations, made of soft and elastically yielding material suitable to adapt to the shape of the sole of the user's foot while walking.

1 . An insole for shoes comprising, associated one another,
 a resting layer for a sole of a user's foot, made of soft and breathable material,   a padding layer, made of soft and breathable material that can adapt to the shape of the sole of the user's foot,   a layer for absorbing impacts and vibrations, made of soft and elastically yielding material suitable to adapt to the shape of the sole of the user's foot while walking.   
   
   
       2 . The insole for shoes according to  claim 1 , comprising padding inserts at least in a padded region that is selected between the region that corresponds to a heel and a region that corresponds to the plantar arch. 
   
   
       3 . The insole for shoes according to  claim 1 , wherein at least one predefined portion thereof is provided with through holes for the passage of air and moisture at the sole of the user's foot. 
   
   
       4 . The insole for shoes according to  claim 3 , wherein said at least one predefined portion thereof comprises
 a first region, which corresponds to the metatarsal region of the user's foot,   a second region, which corresponds to the plantar arch of the user's foot.   
   
   
       5 . The insole for shoes according to  claim 1 , wherein said resting layer comprises leather. 
   
   
       6 . The insole for shoes according to  claim 1 , wherein said padding layer is made of three-dimensional fabric. 
   
   
       7 . The insole for shoes according to  claim 1 , wherein said absorption layer is made of breathable polymeric material. 
   
   
       8 . The insole for shoes according to  claim 7 , wherein said absorption layer is made of open-cell expanded polyurethane. 
   
   
       9 . The insole for shoes according to  claim 1 , wherein said padding layer and said absorption layer are associated one another by perimetric adhesive bonding, by spraying adhesive. 
   
   
       10 . The insole for shoes according to  claim 1 , wherein said resting layer and a semifinished component, which comprises said padding layer and said absorption layer, are associated by perimetric adhesive bonding by means of spots of glue. 
   
   
       11 . The insole for shoes according to  claim 10 , wherein perimetric edges of said semifinished component are substantially internal to the edges of the perimeter of said resting layer. 
   
   
       12 . The insole for shoes according to  claim 1 , wherein said resting layer, said padding layer and said absorption layer are associated one another by sewing. 
   
   
       13 . The insole for shoes according to  claim 2 , wherein said region that corresponds to the plantar arch is arched, by pretensioning said resting layer upon its association with said semifinished component, so as to have an anatomically contoured profile.
