Polyurethane (PU) has electrical shock resistance properties when used in combination with an RB outsole.
The thick outsole provides warmth to the feet and excellent traction.
The aggressive anti-slip outsole design can adapt to the most rugged terrains.

Heavy-Duty Work Boots: Featuring an overall thickened insulated PU upper and a PU and rubber platform outsole, these ruber work boots offer resistance to oil and acid, providing reliable all-around protection. They are ideal for workers who spend extended periods in cold environments with minimal movement, such as miners, loggers, ice fishers, workers at height and those working on oil and gas drilling rigs. Not suitable for long outdoor walks.

Safety Rubber Work Boots: Designed with a steel toe cap to provide reliable protection against heavy objects and compression, meet ASTM F2413-18 standards, as well as the CSA-Z195 compliant puncture-resistant steel midsoles provide comprehensive protection for feet.

Anti-puncture: Puncture-proof midsole fabric in compliance with CSA-Z195, the rubber work boots can not be pierced when the puncture force is loaded at 1200N.

Insulated Work Boots: The combination of polyurethane (PU) with jacquard cloth, SBR, and a breathable waterproof membrane is highly effective for cold protection, keeps you warm in cold environments.

Long Lasting: In the test, the PU material demonstrates exceptional durability by enduring 50,000 bends at minus 40 degrees without breaking, while retaining its softness, the rubber work boots have a unique technology that provides good support at the ankle position.
