1. A boot, comprising:
an outer layer of stretchable leather;
an outsole;
an oversized toe box supported on the outsole and covered by the outer layer of stretchable leather, the toe box being sized to enclose a substantial thickness of compressible cold insulating material and the corresponding portion of a user's foot without compression of the cold insulating material when the boot is worn;
a layer of compressible cold insulating material in its uncompressed state, the cold insulating material located within the outer layer of stretchable leather outside the toe box and extending into the toe box and having a constant thickness in the toe box and an area outside the toe box and adjacent to the toe box, the cold insulating material secured to an underside of the toe box;
wherein the compressible cold insulating material is a high loft fiber insulation; and
a lining having a first side facing the opposing surface of the cold insulating material and a second side generally facing the upper surface of a portion of a user's foot, the lining extending below the opposing surface of the cold insulating material a sufficient distance that the cold insulating material is not compressed between the toe box and the lining when the boot is worn.
