1. A protective boot liner for custom fitting to a wearer'"'"'s anatomy by means of fluid resin injection and its subsequent solidification and including;
- a boot shell worn over the wearer'"'"'s anatomy to be protected and shaped to the general configuration of said anatomy,an inner liner within the boot shell and coextensive with at least one anatomical area to be protected and forming a bladder for the reception of fluid resin,and a layer of nonporous padding coextensive with the inner liner and disposed within the bladder between the shell and the inner liner and impermeable to said fluid resin and having at least one opening at a select area of said anatomy,there being fluid resin injection means to fill the bladder surrounding the padding and over said opening in the padding, thereby inflating the bladder and contiguously engaging the inner liner with the wearer'"'"'s anatomy and to set thereat by subsequent solidification.

Abstract
A protective liner custom fitted by low pressure fluid injection over a wearer'"'"'s anatomy, by permeation of select areas of porous padding, surrounding areas of nonporous padding, with an impervious membrane occluding portions of the porous padding to control fluid resin penetration, and with scarfed abuttment of padding for gradual softness variation; including a method by which a pair of liners are simultaneously injected with fluid resin while the wearer'"'"'s anatomy is in place, for hardening of the fluid resin and of the permeated padding.

9. A protective boot liner for insertion into and custom fitting to a wearer'"'"'s anatomy by means of fluid resin injection and its subsequent solidification and including;
-
an outer liner for insertion into a boot shell worn over the wearer'"'"'s anatomy to be protected and shaped to the general configuration of said anatomy, an inner liner complementary to and within the outer liner and sealed therewith forming a bladder coextensive with at least one anatomical area to be protected and for the reception of fluid resin, and a layer of nonporous padding coextensive with the inner liner and disposed within the bladder between the outer liner and the inner liner and impermeable to said fluid resin and having at least one opening at a select area of said anatomy, there being fluid resin injection means to fill the bladder surrounding the padding and over said opening in the padding, thereby inflating the bladder and contiguously engaging the outer liner with said boot shell and the inner liner with the wearer'"'"'s anatomy and to set thereat by subsequent solidification. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A protective boot liner and method for custom fitting to a wearer'"'"'s anatomy by means of fluid resin injection and its subsequent solidification and including;
-
applying a boot shell to and to be worn over the wearer'"'"'s anatomy to be protected and shaped to the general configuration of said anatomy, inserting an inner liner within the boot shell and coextensive with at least one anatomical area to be protected and forming a bladder for the reception of fluid resin, disposing a layer of nonporous padding coextensive with the inner liner and within the bladder between the shell and the inner liner and impermeable to said fluid resin and having at least one opening at a select area of said anatomy, and injecting fluid resin at a low pressure to fill the bladder surrounding the padding and over said opening in the padding to sufficiently inflate the bladder and contiguously engage the inner liner with the wearer'"'"'s anatomy and to set thereat by subsequent solidification. - View Dependent Claims (18, 19, 20)
