Abstract

A comfort system for Cowboy and work boots, including an insole chassis, an insole chassis backing board, and cushioning pads for absorbing and attenuating shocks encountered by a wearer of the boots. Cushioning pads are secured to a surface of the insole chassis backing board, and apertures in the insole chassis allow the cushions to pass through. Additional cushioning pads are retained in recesses in the midsole. Pads on insole chassis backing board and midsole are vertically aligned. A steel toe inset is utilized in conjunction with the comfort system for work boots. A rim may depend below the midsole to receive a foamed plastic pad.

Claims

1. A boot comprising:

a) an upper,

b) a comfort system located within said upper,

c) said comfort system comprising;

1) an insole chassis,

2) a first aperture extending through said insole chassis in the vicinity of the foot of a wearer of the boot,

3) an insole chassis backing board,

4) a first cushioning layer secured to said insole chassis backing board and passing through said aperture in said insole chassis,

5) a second cushioning layer located on a midsole,

d) said upper being secured to said comfort system along a welt line as part of a welting system.

2. A boot as defined in claim 1 wherein the first cushioning layer comprises first and second cushioning pads.

3. A boot as defined in claim 1 wherein the second cushioning layer comprises third and fourth cushioning pads.

4. A boot as defined in claim 1 wherein the first cushioning layer has a thickness that does not exceed a thickness of the insole chassis.

5. A boot as defined in claim 1 wherein an insole filler layer formed of foamed plastic is located between said insole chassis backing board and said midsole to press downwardly upon said second cushioning layer when the boot is worn.

6. A boot as defined in claim 1 wherein score lines are formed in said insole chassis backing board to impart flexibility to said board.

7. A boot as defined in claim 6 wherein said score lines are formed in said insole chassis backing board in the vicinity of the ball and heel of a wearer of the boot.

8. A boot as defined in claim 1 wherein said first and second cushioning layers each comprise sections located in the area of the ball of the foot that are formed of a foamed plastic with a rebound characteristic.

9. A boot as defined in claim 1 wherein said first and second cushioning layers each comprise sections located in the area of the heel that are formed of a foamed plastic with a shock absorbing characteristics.

10. A boot as defined in claim 1 wherein a filler pad of foamed plastic is located beneath said midsole to attenuate or absorb shock.

11. A boot, as defined in claim 1 wherein recesses are formed on an upper surface of said midsole to receive said second cushioning layer.

12. A comfort system for a boot, said system being adapted for insertion into the interior of a boot, said system comprising:

a) an insole chassis,

b) a first aperture extending through said insole chassis in the vicinity of the foot of a wearer of the boot,

c) an insole chassis backing board,

d) a first cushioning layer secured to said insole chassis backing board and passing through said aperture in said insole chassis,

e) a midsole located beneath said insole chassis backing board, and

f) a second cushioning layer located on said midsole.

13. A comfort system as defined in claim 12 wherein said first and second cushioning layers contain pads in the vicinity of the heel of the wearer that are generally elliptical in shape.

14. A comfort system as defined in claim 12 wherein said first and second cushioning layers contain pads in the vicinity of the ball of the foot that include a leading edge, a trailing edge, and one sidewall that is perpendicular to said leading and trailing edges.

15. A cushioning system as defined in claim 14 wherein a second side wall tapers inwardly from said leading edge toward said trailing edge.

16. A comfort system as defined in claim 12 wherein score lines are formed in said insole chassis backing board to impart flexibility to said board.

17. A comfort system as defined in claim 12 wherein the first cushioning layer has a thickness that does not exceed a thickness of the insole chassis.

18. A comfort system as defined in claim 12 wherein the first cushioning layer is glued to an upper surface of the insole chassis backing board.

19. A comfort system as defined in claim 12 wherein the midsole is a horseshoe shape that is contained entirely beneath a ball of a foot of a wearer of the comfort system.

20. A comfort system for a boot, said system being adapted for insertion into the interior of a boot, said system comprising:

a) an insole chassis,

b) a first aperture extending through said insole chassis in the vicinity of the foot of a wearer of the boot,

c) an insole chassis backing board, and

d) a first cushioning layer secured to said insole chassis backing board and passing through said aperture in said insole chassis.
