Abstract

A boot has an upper portion and a sole. The sole has upper and lower surfaces, and provides an electrical path from the upper surface to the lower surface. An insert has an H-shaped portion in electrical communication with the upper surface of the sole and a tail. The tail can be connected to the leg of coveralls. Electric charges can flow between the tail and the boot sole.

Claims

1. A boot comprising:

an upper portion;

a sole having upper and lower surfaces, the sole being operably connected to the upper portion and configured to provide an electrical path from the upper surface to the lower surface, the sole and the upper portion forming a heel portion;

an insert having a first portion in electrical communication with the upper surface of the sole and a second portion configured to project upward from the upper surface of the sole; and

wherein the first portion of the insert has an H-shape with an elongated strip, a forward cross-member, and a rear cross-member, the rear cross-member being proximal to the heel.

2. The boot of claim 1 wherein the sole has a side wall, the forward cross-member has oppositely disposed end portions, and the rear cross-member has oppositely disposed end portions, the oppositely disposed end portions of the forward and rear cross-members extending upward along the side wall of the sole.

3. The boot of claim 2 wherein the oppositely disposed end portion of the forward and rear cross-members are fastened to the side wall of the sole.

4. The boot of claim 3 wherein the oppositely disposed end portions are stitched to the side wall of the sole with an electrically-conductive thread.

5. The boot of claim 3 wherein the only portion of the insert that is fastened to the sole is the oppositely-disposed end portions.

6. The boot of claim 3 wherein the inner surface of the sole defines grooves and the elongated strip, forward cross-member, and rear cross-member are positioned in the grooves.

7. The boot of claim 1 further comprising a tail extending from the insert.

8. The boot of claim 7 wherein the length of the tail is between about 20 inches and about 36 inches.

9. The boot of claim 8 further comprising a snap operably connected to the tail portion.

10. The boot of claim 1 wherein the insert is formed with carbon material.

11. A boot comprising:

an upper portion formed from an electrically conductive material;

a sole having upper and lower surfaces, the sole being operably connected to the upper portion and configured to provide an electrical path from the upper surface to the lower surface; and

an insert having a first portion in electrical communication with the upper surface of the sole and a second portion configured to project upward from the upper surface of the sole.

12. The boot of claim 11 wherein the upper is in electrical communication with the sole.

13. The boot of claim 11 further comprising at least one snap operably connected to the upper.

14. A boot comprising:

an upper portion formed from an electrically conductive material;

a sole operably connected to the upper portion, the sole being formed from an electrically conductive material; and

an insert having a first portion in electrical communication with the sole and a second portion configured to project upward from the sole.

15. The boot of claim 14 wherein the insert is adjoining the sole.
