The boots have a full-grain cow nubuck leather upper, a breathable sandwich air mesh lining, and an EVA-coated mesh insole. They have a composite toecap and a Kevlar midsole plate for enhanced protection. Compliant with CE EN ISO 20345: 2011 S3 SRC/ HRO standards, they are suitable for construction, logistics, mechanics, workshops, oil & gas, and chemical factories.
General information :
Composite Toe Cap Protection
It is made with light weight fiber-glass material, which can reach 200 joules from falling or rolling objects. It is stronger and lighter than steel toecap.
Kevlar Plate Protection
Kevlar midsole plate, is zero-penetration resistant. It can resist 1100 newtons nail puncture from sharp objects. It is stronger and more flexible than steel plate.
Water Resistant Cow Leather Upper
High quality full grain cow leather with thickness 1.6-1.8mm. It is treated with water resistant coating to protect feet from raining workday. Tear strength is required 10% higher than Europe test requirement, to reach longer lifespan.
Heavy Duty PU/Rubber Outsole
The outsole is made with PU/Rubber material. The midsole is 45‡5 degree hardness PU, which is soft and shock absorption. The outsole is natural rubber with 5%-10% nitrile, which can pass 300 °C heat resistant HRO test.
Insole memory foam: they take the impression memory of your feet shape, and provides cushioning to each part of your feet.
