Several of our safety toe boots have high-voltage resistance in accordance with ASTM F 2413-2011 and CAN/CSA Z 195-2014 to protect your feet from shocks. Both certifications require testing for electrical hazard resistance to 18,000 Kilovolts. A common misconception with EH rated safety boots is that metal in the boots is bad. The reality is that metal is only conductive when it comes in contact with other metal. Any HAIX® boot with steel toes or steel shanks are all enclosed with a non-conductive material like leather and rubber, so you can rest assured that you stay protected with the best boots for shock protection!
