An insole (10) for a boot or the like has a cavity (32) in the padding layer (30) for holding a heat source (42) that produces heat from an exothermic chemical reaction. The cavity (32) is preferably located in the toe portion (16) of the padding layer (30). The upper layer (18) of the insole (10) preferably has a plurality of holes (33) therein for facilitating heat transfer from the heat source (42) to the foot of a person using the insole (10). A pull cord (26) may be connected to the stabilizer layer for facilitating removal of the insole (10) from a boot or the like. |
