Abstract

An insole having a top sheet and a base layer with three pieces that include a base layer, a forefoot pad made of a clear TPR gel and a mid-foot to heel cushion made of a supersoft polyurethane. The midfoot/heel surface has a raised arch with criss-crossing longitudinal curvilinear indentations, a flattened midfoot area with a metatarsal midfoot tear-drop raised area, and a heel cup that surrounds the exterior back of the heel. A heel pod opening goes through the entirety of the thickness of base layer of the insole body and a heel pad is affixed to the bottom surface of the base layer being made of a clear TPR gel or blown EVA. There is also a supersoft heel dome and a metatarsal raised dome on the top (foot contact) surface of the insole which would be directly above the heel pod and the metatarsal midfoot area, respectively.

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 midfoot-to-heel stability cushion 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 cushion therein;
(c) a heel dome on the top surface of the base layer and raised over the heel area of the insole;
(d) a metatarsal dome on the top surface of base layer and raised over the metatarsal midfoot area of the insole;
(e) separation wall on the bottom surface of the base layer and located between said forefoot pad indentation area and said midfoot-to-heel stability cushion indentation area
a stability cushion positioned on the bottom surface of the base layer in the stability cushion indentation area and having a raised arch support on the bottom surface of the insole in the medial arch area, a heel cup on the bottom surface of the insole and surrounding the heel end of the insole with vertical walls, a metatarsal arch dome raised up from the bottom surface of the insole, and a heel pad aperture on the bottom surface of the base layer in the heel area,
said raised arch support having a first set of curvilinear indentations on the bottom surface of the insole in medial arch area and extending generally lengthwise in a longitudinal toe-to-heel direction at a first angle of inclination from the longitudinal axis of the insole;
said raised arch support having a second set of curvilinear indentations on the bottom surface of the insole in medial arch area and extending generally lengthwise in a longitudinal toe-to-heel direction at a second angle of inclination from the longitudinal axis of the insole, said first angle of inclination and said second angle of inclination not being equal,

a forefoot pad positioned on the bottom surface of the insole in the forefoot indentation area;
a heel pad positioned in the heel pad aperture of the stability cushion, and extending through the stability cushion to be secured to the bottom surface of the base layer;
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 first angle of inclination is 5-65 degrees compared to said longitudinal axis of said insole and said second angle of inclination is 15-85 degrees compared to said longitudinal axis of said insole.

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 20-35 Asker±3.

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

10. The insole of claim 1 , wherein said heel pad aperture is surrounded by a flat midfoot/heel surface with surrounding grooves.

11. The insole of claim 1 , wherein base layer is made of a durable nylon fabric.

12. The insole of claim 1 , wherein said first longitudinal indentations have a groove depth of approximately 0.50 mm-1.5 mm.

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

14. 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.

15. 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.

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

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

18. 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 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 midfoot-to-heel stability cushion 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 cushion therein;
a stability cushion positioned on the bottom surface of the base layer in the stability cushion area and having a raised arch support on the bottom surface of the insole in the medial arch area, a heel cup on the bottom surface of the insole and surrounding the heel end of the insole with vertical walls, a metatarsal arch dome raised up from the bottom surface of the insole, and a heel pad aperture on the bottom surface of the base layer in the heel area,
said raised arch support having a first set of curvilinear indentations on the bottom surface of the insole in medial arch area and extending generally lengthwise in a longitudinal toe-to-heel direction at a first angle of inclination from the longitudinal axis of the insole;
said raised arch support having a second set of curvilinear indentations on the bottom surface of the insole in medial arch area and extending generally lengthwise in a longitudinal toe-to-heel direction at a second angle of inclination from the longitudinal axis of the insole, said first angle of inclination and said second angle of inclination not being equal,

a forefoot pad positioned on the bottom surface of the insole in the forefoot area;
a heel pad positioned in the heel pad aperture of the stability cushion, and extending through the stability cushion to be secured to the bottom surface of the base layer;
a top sheet that extends across the top surface of the base layer from the heel end to the toe end of the insole.

19. The insole of claim 18 , wherein said base layer has separation wall on the bottom surface of the base layer and located between said
