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) a cover layer,

2) an insole chassis,

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

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

5) an insole chassis backing board,

6) first and second cushioning pads secured to said insole chassis backing board and passing through said first and second apertures in said insole chassis,

7) third and fourth cushioning pads located on a midsole,

8) said third and fourth cushioning pads being in vertical alignment with said first and second cushioning pads beneath the ball of the foot and the heel of foot of a wearer to cushion impact while walking in said boot,

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 an insole filler layer formed of foamed plastic is located between said insole chassis lining backing board and said midsole to press downwardly upon said third and fourth cushioning pads when the boot is worn.

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

4. A boot as defined in claim 3 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.

5. A boot s defined in claim 1 wherein said cushioning pads located in the area of the ball of the foot are formed of a foamed plastic with a rebound characteristic.

6. A boot as defined in claim 1 wherein said cushioning pads located in the area of the heel are formed of a foamed plastic with a shock absorbing characteristics.

7. A boot as defined in claim 1 further including an orthotic insert that is seated atop said comfort system, said insert being removable for cleaning.

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

9. A boot as defined in claim 8 wherein a rim depends from the under surface of said midsole, and said filler pad fits within said rim.

10. A boot, as defined in claim 1 further including a midsole with an upper surface and a lower surface, and recesses are formed on the upper surface of said midsole to receive said third and fourth cushioning pads.

11. A boot, as defined in claim 1, wherein said cover layer extends from the heel of the wearer toward the ball of the foot of the wearer.

12. A boot, as defined in claim 11, wherein said cover layer s formed of a shock absorbing plastic.

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

a) a cover layer,

b) an insole chassis,

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

d) a second aperture extending through said insole chassis in the vicinity of the heel of the foot of a wearer of the boot,

e) an insole chassis backing board,

f) first and second cushioning pads secured to said insole chassis backing board and passing through said first and second apertures in said insole chassis,

g) a midsole located beneath said insole chassis backing board,

h) third and fourth cushioning pads located on said midsole,

i) said third and fourth cushioning pads being in vertical alignment with said first and second cushioning pads beneath the ball of the foot and the heel of the wearer to cushion impact while walking in a boot.

14. A comfort system as defined in claim 13 wherein said pads in the vicinity of the heel of the wearer are generally elliptical in shape.

15. A comfort system as defined in claim 13 wherein said pads in the vicinity of the ball of the foot include a leading edge, a trailing edge, and one side all is perpendicular to said leading and trailing edges.

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