With heat resistance to 572°F, safety boots with Steel Blue’s Nitrile Outsole are great for working in very hot conditions (such as remote mine sites or on asphalt and steel plates), or situations where the sole of your work boots may come into contact with hot objects (welding).
The Nitrile Outsole is made from a type of higher heat resistant rubber and forms the outer layer of your work boots. At these high temperatures, there’s a 60-second threshold before it reaches melting point.
With superior resistance to abrasion and excellent tear strength, the slip resistant capabilities of Steel Blue’s Nitrile Outsole actually improves with wear. It’s also highly resistant to oil, mild acids and alkalis.
All Steel Blue safety boots featuring our Nitrile Outsole comply with American Safety Footwear Certification ASTM F2413 while our Soft Toe work boots featuring the Nitrile Outsole comply with American Safety Footwear Certification ASTM F2892.
