These boots are among the lightest thermo-boots in the world today. Each pair weighs just 2 lbs., 2 oz. They are made from EVA, affording good insulation and a light weight. They are ideal for cold environments and can withstand temperatures as low as -31°F. They have steel toecaps and special Kevlar plates in the sole. They also have shock absorbers in the toes, soles and heels, to increase safety, comfort, agility and elasticity. The boots feature anti-slip protection to ensure workers do not slip or fall. They are particularly resistant to fat and oil.
