b) a padded sole member having ventilation means; c) an insole assembly for a shoe, which is disposed below said padded sole member with which it is fixed by insertion, said sole assembly comprising: a baricentric oversole with hollow sections predefined in the plantar and tarsal regions, in which hollow sections some lower portions, of complementary design, of said padded sole member are inserted; an intersole placed below said baricentric oversole having flexure lines below the area where the foot bends to make a step; an interior band metatarsal disposed below said intersole to provide rigidity and structure to the metatarsal arch and bridge of the wearer; and a reinforcing web under the band to reinforce the elements comprising said sole assembly; d) an antiskid damping sole disposed below said sole assembly, said damping sole comprising a sole element with a hollow section, an elastometric element with multiple holes, and a piece having an antiskid lower surface and an upper surface on which a plurality of elements upwardly extend to engage with said holes in the elastomeric element; said piece configured for insertion into the hollow section of the sole element and e) a heel having means for dampening in the heel zone the impact of the step when walking. ### Claim 2 (depends on 1) The integral system of claim 1, wherein said ventilation means consists of multiple through holes provided in plantar, tarsal and metatarsal regions in said sole member, and a plurality of channels in air flow communication with said holes to form jointly air circulation paths to keep the wearer's foot dry. ### Claim 3 (depends on 1) The integral system of claim 1, wherein said padded sole member has thickened lower portions located on the plantar and tarsal regions thereof. ### Claim 4 (depends on 1) The integral system of claim 1, wherein said padded sole member further includes a flange on the tarsal region adapted to conform anatomically to the wearer's heel. ### Claim 5 (depends on 1) The integral system of claim 1, wherein said padded sole member is made of an integral piece. ### Claim 6 (depends on 1) The integral system of claim 1, wherein said padded sole member is replaceable when it loses its elastic characteristics. ### Claim 7 (depends on 1) The integral system of claim 1, further including an anatomically shaped overinsole attached firmly above the padded sole member. ### Claim 8 (depends on 7) The integral system of claim 7, wherein the overinsole includes an antibacterial liner and biomagnetics sensing elements. ### Claim 9 (depends on 1) The integral system of claim 1, wherein said heel comprises a) a heel body having a bore extending longitudinally throughout said heel body, first and second recesses provided at the lower and upper ends, respectively, of said heel body; and a hollow, elongated structural reinforcement of resistant material covering the wall of said bore; and b) a dampening cap assembly comprising: i) a removable cap element with an insertion rod fixed firmly on one end of said cap element; said rod is insertable in said bore through a lower opening in said heel body so that a threaded opposite end of said rod protrudes up to the second recess in said heel body for threaded connection with a fastening element; ii) a protection cap secured firmly by adjusting it to the lower end of the heel body, said cap having a groove and a hole in register with the heel body bore; iii) a piece of elastomeric material with a hole, said rod being adapted to mate with the hole until it rests in the removable cap, said elastomeric piece and the removable cap being sized so that the elastomeric piece is completely housed in said cap; said removable cap is partially inserted in first recess of the protection cap; and iv) an annular gasket element being sized to fit around the insertion rod to stay placed between the point of contact of the protection cap with the bottom of said first recess. ### Claim 10 (depends on 9) The integral system of claim 9, wherein the protection cap further has a journal to be inserted tightly in the first recess of the heel bore to fix said cap in the heel body. ### Claim 11 (depends on 9) The integral system of claim 9, wherein the cap element is replaceable when said element wears out with the use. ### Claim 12 (depends on 9) The integral system of claim 9, wherein the elastomeric piece is replaceable when it loses its elastic properties due to its use. ### Claim 13 (depends on 1) The integral system of claim 1, wherein the padded insole comprises an integral piece of elastomeric material including an air ventilation system comprising a plurality of holes passing through the elastomeric piece in the plantar, tarsal and metatarsal regions, and a plurality of channels in flow communication with said holes to promote jointly the circulation of air all over the foot's sole. ### Claim 14 (depends on 13) The elastomeric insole of claim 13, further including padding parts thickened on the lower surface of the same or just on the tarsal and plantar zones thereof. ### Claim 15 (depends on 13) The integral system of claim 13, further including a flanged portion in the tarsal region to fit to the user's heel. ### Claim 16 (depends on 13) The integral system of claim 13, wherein the insole is made of one piece. ### Claim 17 (depends on 13) The integral system of claim 13, wherein the insole can be replaced when it loses its elastomeric characteristics. ### Claim 18 A heel for a women's high heeled shoe, including a system to dampen the impact caused when walking, said heel comprising: a) a heel body with a bore extending longitudinally through it and first and second recesses located at the ends of said bore; said heel body further comprises a hollow structural reinforcement made of resistant material, which covers the wall of said bore; and b) a dampening cap assembly comprising: i) a removable cap with an insertion rod fixed firmly on one of its ends to said cap, the opposed end of said rod is threaded and is inserted in the heel body bore through the lower end of said heel, the threaded rod end protruding up to the second recess of the heel body to be grasped by a grasping element; ii) a grasping element connected to said threaded rod end to hold the removable cap inserted in said heel body; iii) a protection cap firmly adhered by engagement at the lower end of the heel body, said cap having a recess and a hole being in register with the heel bore; iv) an elastomeric piece having a hole, said piece adapted to mate with the rod such that said piece remains in contact with the removable cap; said elastomeric piece and said removable cap are sized in such a manner that the elastomeric piece is totally lodged in said first recess of the protection cap, while the removable cap is housed, at least in part, in said first recess; and v) an annular gasket inserted around the insertion rod to be placed between the contact point of the protection cap with the bottom of the first recess of the heel bore. ### Claim 19 (depends on 18) The integral system of claim 18, wherein the protection cap further includes a journal to be inserted in said first recess of the heel body to secure said cap in this body. ### Claim 20 (depends on 18) The integral system of claim 18, wherein the cap is replaceable when said element wears out with use. ### Claim 21 (depends on 18) The integral system of claim 18, wherein the elastomeric piece is replaceable when it looses its elastic characteristics due to its use.
