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:

an upper,

a comfort system located within said upper,

said comfort system comprising;

an insole chassis,

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

an insole chassis backing board,

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

a second cushioning layer located on a midsole,

said upper being secured to said comfort system along a welt line as part of a welting system and

wherein the first cushioning layer has a thickness that does not exceed a thickness of the insole chassis.

2. A boot comprising:

an upper,

a comfort system located within said upper,

said comfort system comprising;

an insole chassis,

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

an insole chassis backing board,

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

a second cushioning layer located on a midsole,

said upper being secured to said comfort system along a welt line as part of a welting system and

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.

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

an insole chassis,

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

an insole chassis backing board,

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

a midsole located beneath said insole chassis backing board, and

a second cushioning layer located on said midsole,

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, and

wherein a second side wall tapers inwardly from said leading edge toward said trailing edge.
