Abstract

An insole having a top sheet, a base layer, a forefoot pad, a heel cushion, and stability cradle. The forefoot pad can be made a blown EVA or other material, and the heel cushion can be made of a clear TPR, soft polyurethane or blown EVA. A heel cup surrounds the exterior back by a heel cup, and a heel pod opening and midfoot pod opening is located in the stability cradle for allowing placement of heel pads and midfoot pads in a replacement manner. There is also a soft metatarsal raised dome on the top (foot contact) surface of the insole which would be directly above the metatarsal midfoot area.

First claim

The invention claimed is:

1. A contoured insole used inside a shoe and having a top side that contacts the users foot, a bottom side that contacts the interior of a shoe after insertion therein, a lateral side that lies adjacent to the outer side of a user's foot in use and a medial side that lies adjacent the inner side, or arch, of a user's foot, said insole comprising:
a base layer having a contoured shape which receives and supports the foot of the user, a heel end, a toe end, a top surface, a bottom surface, a lateral side and a medial side, said lateral and medial sides extending approximately from said heel end to said toe end, said base layer having:
(a) a forefoot pad indentation area on the bottom surface of the insole extending from the midfoot to the toe area of the base layer and supporting the insertion of a forefoot pad therein,
(b) a stability cradle indentation area on the bottom surface of the insole extending from the midfoot to the heel area of the insole and supporting the insertion of a stability cradle therein;
(c) a metatarsal dome on the top surface of base layer and raised over the metatarsal midfoot area of the insole;
(d) separation wall on the bottom surface of the base layer and located between said forefoot pad indentation area and said mid-foot-to-heel stability cradle indentation area

a stability cradle positioned on the bottom surface of the base layer in the stability cradle indentation area and having:
(a) a raised arch support on the bottom surface of the insole in the medial arch area,
(b) a heel cup on the bottom surface of the insole and surrounding the heel end of the insole with vertical walls,
(c) a first set of elongated, transverse ribs in a raised medial arch, said raised medial arch extending continuously along an inner side of the stability cradle,
(d) a second set of vertical support ribs surrounding the heel cup,
(e) a third set of vertical support ribs aligned in a lateral midfoot area, said lateral midfoot area extending continuously along an outer side of the stability cradle,
(f) a midfoot pad aperture on the bottom surface of the stability cradle in the midfoot area, and
(g) a heel pad aperture on the bottom surface of the stability cradle in the heel area,

a forefoot pad positioned on the bottom surface of the insole in the forefoot indentation area;
a medial heel pad positioned on the medial side of the heel pad aperture in the stability cradle;
a lateral heel pad positioned on the medial side of the heel pad aperture in the stability cradle;
a midfoot heel pad positioned in the midfoot pad aperture in the stability cradle; and,
a top sheet that extends across the top surface of the base layer from the heel end to the toe end of the insole.

2. The insole of claim 1 , wherein said base layer is formed of a gel material.

3. The insole of claim 1 , wherein said base layer is made of polyurethane polyester glycol with a hardness 10-30 Asker±3.

4. The insole of claim 1 , wherein said forefoot pad made of a clear TPR gel (thermoplastic rubber).

5. The insole of claim 4 , wherein said TPR gel has a hardness rating of 10-20 Asker±3.

6. The insole of claim 1 , wherein said forefoot pad has a groove pattern with a width spacing of approximately 1.0 mm-1.50 mm.

7. The insole of claim 1 , wherein said heel pad is made of pre-blown EVA (ethylene-vinyl acetate) material.

8. The insole of claim 7 , wherein said heel pad has a hardness rating of 10-35 Asker±3.

9. The insole of claim 1 , wherein said top sheet is made of 65% Nylon/35% polyester.

10. The insole of claim 1 , wherein said metatarsal dome on the top side of the insole matches the upwardly-curved metatarsal arch dome on the bottom surface of the insole.

11. The insole of claim 1 , wherein said separation wall located on the bottom surface of the base layer and is approximately 1 mm in height.

12. The insole of claim 1 , wherein said forefoot and heel pads are made of rubber or synthetic rubber.

13. The insole of claim 1 , wherein said forefoot and heel pads are made of a neoprene synthetic rubber.

14. A contoured insole used inside a shoe and having a top side that contacts the users foot, a bottom side that contacts the interior of a shoe after insertion therein, a lateral side that lies adjacent to the outer side of a user's foot in use and a medial side that lies adjacent the inner side, or arch, of a user's foot, said insole comprising:
a base layer having a contoured shape which receives and supports the foot of the user, a heel end, a toe end, a top surface, a bottom surface, a lateral side and a medial side, said lateral and medial sides extending approximately from said heel end to said toe end, said base layer having:
(a) a forefoot pad indentation area on the bottom surface of the insole extending from the midfoot to the toe area of the base layer and supporting the insertion of a forefoot pad therein,
(b) a stability cradle indentation area on the bottom surface of the insole extending from the midfoot to the heel area of the insole and supporting the insertion of a stability cradle therein;
(c) a metatarsal dome on the top surface of base layer and raised over the metatarsal midfoot area of the insole;
(d) separation wall on the bottom surface of the base layer and located between said forefoot pad indentation area and said mid-foot-to-heel stability cradle indentation area

a stability cradle positioned on the bottom surface of the base layer in the stability cradle indentation area and having:
(a) a raised arch support on the bottom surface of the insole in the medial arch area,
(b) a heel cup on the bottom surface of the insole and surrounding the heel end of the insole with vertical walls,
(c) a first set of elongated, transverse ribs in a raised medial arch, said raised medial arch extending continuously along an inner side of the stability cradle,
(d) a second set of vertical support ribs surrounding the heel cup,
(e) a third set of vertical support ribs aligned in a lateral midfoot area, said lateral midfoot area extending continuously along an outer side of the stability cradle,
(f) a midfoot pad aperture on the bottom surface of the stability cradle in the midfoot area, and
(g) a heel pad aperture on the bottom surface of the stability cradle in the heel area,

a forefoot pad positioned on the bottom surface of the insole in the forefoot indentation area;
a medial heel pad positioned on the medial side of the heel pad aperture in the stability cradle;
